Structure and Properties of Matter
Atoms are the building blocks of matter. Matter has physical and chemical properties that determine its structure and behavior. The states of matter are solid, liquid, and gas.
Structure and properties of Matter
Atoms: The smallest unit of matter that still retains the properties of an element
Molecules: Two or more atoms held together by chemical bonds
Physical Properties: Characteristics of a substance that can be observed without changing its identity
Did you know?
Matter is made up of atoms, which are the smallest building blocks found in nature and can be as small as one billionth of a meter. The atom is made up of three particles called protons, neutrons, and electrons. The protons and neutrons are in the nucleus of the atom while the electrons orbit around it like planets around the sun.

Question: What is the difference between the structure and properties of solids, liquids and gases?
Solids have a fixed shape and volume. Liquids take the shape of their container and have a fixed volume. Gases take the shape and volume of their container.
A: Draw a diagram to show the difference between solids, liquids and gases. B: Explain the differences in terms of particles and energy.
