Metals & Non-Metals

Metals and Non-Metals

The elements in the periodic table can be roughly divided into metals and non-metals. There are more metals than non-metals in the periodic table. In the periodic table below, metals are red and non-metals are green.

Metals

Metals are found on the left of the periodic table because they have few electrons in their outer shell.
When metals react, they lose 1 or more of these negatively charged electrons to form positively charged ions.

Properties of metals

Metals have high melting and boiling points.
Metals are good conductors of heat and electricity.
Metals are all solids (except for mercury) at room temperature.
Metals form metal oxides when they react with oxygen. Metal oxides are alkaline.

Non-metals

Non-metals are found on the right of the periodic table because they have many electrons in their outer shell.
When non-metals react, they either:
- Gain electrons to form negatively charged ions.
- Or share electrons to form neutral molecules.

Properties of non-metals

Non-metals have lower melting and boiling points than metals.
Non-metals are often found as gases.
Non-metals generally do NOT conduct heat or electricity.
Non-metals form non-metal oxides when they react with oxygen. Non-metal oxides are acidic.
