Elements are the basic building blocks of matter. Each element is made up of one type of atom which determines its properties. An atom is the smallest particle or component of an element that still has the same properties of that element.

Use a reference to color metals blue, metalloids yellow, and nonmetals green.

The Periodic Table groups elements in an organized fashion.

Elements in each column or group have similar chemical properties. Elements in each row or period are arranged according to the number of protons. The number of protons increases from left to right.

A molecule is the smallest unit of a substance formed when two or more atoms join together chemically. Many substances occur in nature as molecules and not as single atoms. Examples include oxygen (O2) and nitrogen (N2) molecules.

A compound is a substance that contains two or more different elements chemically joined together. Water is an example of a compound (H2O).

A mixture is the combination of two or more different substances that do not bond to form a compound. Mixtures are only physically combined and can be separated. An example of a mixture is a bowl with a variety of nuts.

A solution is a type of mixture. Salt dissolved in water is one example – the salt is the solute and the water is the solvent.
