What is Metals and Non-Metals?
Within Chemistry, which covers atoms, bonding, reactions, the periodic table, organic chemistry and the chemistry of everyday life, this topic explains Metals and Non-Metals. Chemistry links what you can see in the lab to the particles and bonds behind it, so each topic here shows that link in a model.
Check that you can explain Metals and Non-Metals in your own words and give one example from everyday life. If you can do that, you have understood the core idea.
Understanding Metals and Non-Metals helps you explain why substances behave as they do, from cleaning products and food to medicines.
Metals and Non-Metals in detail
Metals are usually shiny, malleable, ductile, good conductors of heat and electricity and form positive ions by losing electrons. Non-metals are usually dull, brittle when solid, poor conductors (graphite is an exception) and form negative ions or share electrons.
Metal oxides are generally basic, and non-metal oxides are generally acidic. The metals are on the left of the periodic table, separated from the non-metals by a staircase line, with a few metalloids such as silicon in between. These differences explain the uses of materials in electronics, construction and packaging.
