Matter is best described as anything that occupies space and has mass. Matter exists in four different states, which are solid, liquid, gas, and plasma. The state of matter an object is in is determined by several factors: temperature, pressure, and molecular composition. Solids have a definite shape and volume. Liquids have a definite volume but not a definite shape. Gases have neither a definite shape nor a definite volume. Plasma is a superheated gas that is often called “the fourth state of matter.”
Matter is composed of atoms, which are the basic building blocks of all matter. Atoms are made up of protons, neutrons, and electrons. Protons and neutrons are found in the nucleus of the atom, while electrons orbit the nucleus. The number of protons in an atom determines what element it is. For example, all atoms with one proton are hydrogen atoms, all atoms with two protons are helium atoms, and so on. The number of neutrons in an atom can vary, which gives rise to different isotopes of the same element.
Matter can be classified into two types: pure substances and mixtures. Pure substances are substances that have a definite chemical composition and a definite set of properties. Mixtures are substances that are made up of two or more pure substances. The properties of a mixture depend on the properties of the pure substances that make it up.

Matter is anything that occupies space and has mass.
- Occupies space
- Has mass
- Exists in four states
- Solid, liquid, gas, plasma
- Made up of atoms
- Atoms have protons, neutrons, electrons
- Protons determine element
- Neutrons affect isotope
- Classified as pure or mixture
- Pure: definite composition
Matter is all around us. It makes up everything we see, touch, and feel. It is the stuff that makes up the universe.
Occupies space
One of the defining characteristics of matter is that it occupies space. This means that matter takes up room and cannot be in two places at the same time. The amount of space that matter occupies is called its volume. Volume is measured in cubic units, such as cubic centimeters (cm3) or cubic meters (m3).
The volume of an object depends on its shape and size. For example, a cube with a side length of 10 cm has a volume of 1000 cm3. A sphere with a radius of 10 cm has a volume of approximately 4189 cm3. The volume of an object can also change if its temperature or pressure changes.
When matter is heated, its particles move faster and take up more space. This causes the volume of the matter to increase. For example, when you heat a pot of water, the water expands and takes up more space in the pot. When matter is cooled, its particles move slower and take up less space. This causes the volume of the matter to decrease. For example, when you put a bottle of soda in the freezer, the soda contracts and takes up less space in the bottle.
Pressure can also affect the volume of matter. When pressure is applied to matter, its particles are forced closer together. This causes the volume of the matter to decrease. For example, when you squeeze a balloon, the air inside the balloon is compressed and the volume of the balloon decreases.
The fact that matter occupies space is one of the most fundamental properties of matter. It is this property that allows us to see and touch objects and to measure their size and shape.
Has mass
Another defining characteristic of matter is that it has mass. Mass is a measure of the amount of matter in an object. The greater the mass of an object, the more matter it contains. Mass is measured in units such as grams (g), kilograms (kg), and pounds (lb).
- Mass is a measure of the amount of matter in an object.
The greater the mass of an object, the more matter it contains.
- Mass is a fundamental property of matter.
All matter has mass, regardless of its state or composition.
- Mass can be measured.
There are a variety of ways to measure mass, including using a balance or a scale.
- Mass is conserved.
In a closed system, the total mass of the system remains constant, even if the matter in the system changes form.
Mass is an important property of matter because it affects the way that matter interacts with other matter. For example, objects with greater mass are more difficult to accelerate and decelerate than objects with less mass. Mass also affects the force of gravity between two objects. The greater the mass of two objects, the greater the force of gravity between them.
Exists in four states
Matter can exist in four different states: solid, liquid, gas, and plasma. These states are determined by the temperature and pressure of the matter. When the temperature of a substance is increased, its particles move faster and take up more space. This causes the substance to change from a solid to a liquid to a gas. When the pressure of a substance is increased, its particles are forced closer together. This causes the substance to change from a gas to a liquid to a solid.
- Solid
In a solid, the particles are held together by strong forces and are unable to move freely. Solids have a definite shape and volume.
- Liquid
In a liquid, the particles are held together by weaker forces and are able to move more freely. Liquids have a definite volume but not a definite shape.
- Gas
In a gas, the particles are not held together by any forces and are able to move very freely. Gases have neither a definite shape nor a definite volume.
- Plasma
Plasma is a superheated gas in which the electrons have been stripped away from the atoms. Plasma is often called “the fourth state of matter.” Plasma is found in stars, lightning, and fluorescent lights.
The state of matter that a substance is in can affect its properties. For example, solids are generally harder and denser than liquids, and gases are generally lighter and more fluid than liquids. The state of matter can also affect the way that a substance interacts with other substances.
Solid, liquid, gas, plasma
The four states of matter are solid, liquid, gas, and plasma. Each state of matter has its own unique properties and characteristics.
Solids are characterized by their rigidity and definite shape. The particles in a solid are held together by strong forces and are unable to move freely. Solids have a definite volume and a definite shape. Examples of solids include ice, rock, and metal.
Liquids are characterized by their fluidity and ability to flow. The particles in a liquid are held together by weaker forces than in a solid and are able to move more freely. Liquids have a definite volume but not a definite shape. They take the shape of the container they are in. Examples of liquids include water, oil, and milk.
Gases are characterized by their ability to expand and fill the space they are in. The particles in a gas are not held together by any forces and are able to move very freely. Gases have neither a definite shape nor a definite volume. They expand to fill the container they are in. Examples of gases include air, helium, and hydrogen.
Plasma is a superheated gas in which the electrons have been stripped away from the atoms. Plasma is often called “the fourth state of matter.” Plasma is found in stars, lightning, and fluorescent lights.
The state of matter that a substance is in can affect its properties. For example, solids are generally harder and denser than liquids, and gases are generally lighter and more fluid than liquids. The state of matter can also affect the way that a substance interacts with other substances.
Made up of atoms
All matter is made up of atoms. Atoms are the basic building blocks of matter and cannot be broken down into smaller particles by chemical means. Atoms are so small that they cannot be seen with a microscope. There are over 100 different types of atoms, which are called elements. Examples of elements include hydrogen, oxygen, carbon, and iron.
Atoms are made up of three subatomic particles: protons, neutrons, and electrons. Protons and neutrons are found in the nucleus of the atom, while electrons orbit the nucleus. Protons have a positive charge, electrons have a negative charge, and neutrons have no charge. The number of protons in an atom determines what element it is. For example, all atoms with one proton are hydrogen atoms, all atoms with two protons are helium atoms, and so on.
The number of neutrons in an atom can vary, which gives rise to different isotopes of the same element. Isotopes of an element have the same number of protons and electrons, but they have different numbers of neutrons. For example, carbon-12, carbon-13, and carbon-14 are all isotopes of carbon. They all have six protons and six electrons, but they have different numbers of neutrons (6, 7, and 8, respectively).
Atoms can combine with each other to form molecules. A molecule is two or more atoms that are held together by chemical bonds. Molecules can be very simple, such as the molecule of water (H2O), which is made up of two hydrogen atoms and one oxygen atom. Molecules can also be very complex, such as the molecules of proteins and DNA.
The fact that all matter is made up of atoms is one of the most fundamental principles of chemistry. It explains why matter has the properties that it does and why different substances react with each other in the way that they do.
Atoms have protons, neutrons, electrons
Atoms are made up of three subatomic particles: protons, neutrons, and electrons. Protons and neutrons are found in the nucleus of the atom, while electrons orbit the nucleus. Protons have a positive charge, electrons have a negative charge, and neutrons have no charge.
- Protons determine the element.
The number of protons in an atom determines what element it is. For example, all atoms with one proton are hydrogen atoms, all atoms with two protons are helium atoms, and so on.
- Neutrons affect isotopes.
The number of neutrons in an atom can vary, which gives rise to different isotopes of the same element. Isotopes of an element have the same number of protons and electrons, but they have different numbers of neutrons.
- Electrons determine chemical properties.
The number of electrons in an atom determines the chemical properties of the element. For example, elements with one electron in their outermost shell are very reactive, while elements with a full outermost shell are unreactive.
- Protons and electrons determine mass.
The mass of an atom is determined by the number of protons and neutrons in the nucleus. Protons and neutrons have approximately the same mass, while electrons have very little mass.
The fact that atoms have protons, neutrons, and electrons is one of the most fundamental principles of chemistry. It explains why matter has the properties that it does and why different substances react with each other in the way that they do.
Protons determine element
The number of protons in an atom determines what element it is. This is because the number of protons in an atom determines the number of electrons that the atom has. Electrons are responsible for the chemical properties of an element. For example, all atoms with one electron in their outermost shell are very reactive, while all atoms with a full outermost shell are unreactive.
- Each element has a unique number of protons.
For example, hydrogen atoms always have one proton, helium atoms always have two protons, and oxygen atoms always have eight protons.
- The number of protons determines the atomic number of an element.
The atomic number of an element is the number of protons in the nucleus of an atom of that element.
- The atomic number of an element is unique.
No two elements have the same atomic number.
- The atomic number of an element determines its position on the periodic table.
The periodic table is a chart that organizes all of the known elements according to their atomic number.
The fact that the number of protons in an atom determines the element is one of the most fundamental principles of chemistry. It explains why different elements have different properties and why they react with each other in the way that they do.
Neutrons affect isotope
The number of neutrons in an atom can vary, which gives rise to different isotopes of the same element. Isotopes of an element have the same number of protons and electrons, but they have different numbers of neutrons. For example, carbon-12, carbon-13, and carbon-14 are all isotopes of carbon. They all have six protons and six electrons, but they have different numbers of neutrons (6, 7, and 8, respectively).
- Isotopes have the same atomic number.
This is because they have the same number of protons.
- Isotopes have different mass numbers.
This is because they have different numbers of neutrons.
- Isotopes have the same chemical properties.
This is because they have the same number of electrons.
- Isotopes can be used to study different processes.
For example, carbon-14 is used to date organic materials.
The fact that neutrons affect isotopes is important for a number of reasons. First, it explains why elements can have different isotopes. Second, it allows scientists to use isotopes to study different processes. Third, it has practical applications in a number of fields, such as medicine and archaeology.
Classified as pure or mixture
Matter can be classified as either pure or a mixture. A pure substance is a substance that has a definite chemical composition and a definite set of properties. A mixture is a substance that is made up of two or more pure substances. The properties of a mixture depend on the properties of the pure substances that make it up.
- Pure substances have a definite chemical composition.
This means that they are made up of only one type of atom or molecule.
- Pure substances have a definite set of properties.
These properties include melting point, boiling point, density, and solubility.
- Mixtures are made up of two or more pure substances.
The properties of a mixture depend on the properties of the pure substances that make it up.
- Mixtures can be separated into their pure components.
This can be done by physical means, such as filtration or distillation.
The classification of matter as pure or a mixture is important because it helps us to understand the properties of matter and how matter can be used. For example, pure substances are often used in industrial processes because they have predictable properties. Mixtures are often used in everyday products, such as food and beverages.
Pure: definite composition
A pure substance is a substance that has a definite chemical composition. This means that it is made up of only one type of atom or molecule. For example, water is a pure substance because it is made up of only hydrogen and oxygen atoms. Salt is a pure substance because it is made up of only sodium and chlorine atoms.
The definite chemical composition of a pure substance gives it a definite set of properties. For example, water always freezes at 0 degrees Celsius and boils at 100 degrees Celsius. Salt always melts at 801 degrees Celsius. The properties of a pure substance are always the same, regardless of where it is found or how it is prepared.
Pure substances are often used in industrial processes because they have predictable properties. For example, water is used as a coolant in many industrial processes because it has a high specific heat capacity. Salt is used as a preservative in many foods because it inhibits the growth of bacteria.
Pure substances can also be found in nature. For example, gold is a pure substance that can be found in the earth’s crust. Diamonds are pure substances that are made up of carbon atoms.
The fact that pure substances have a definite composition is important for a number of reasons. First, it allows us to identify and classify pure substances. Second, it allows us to predict the properties of pure substances. Third, it allows us to use pure substances in a variety of applications.
