Task: On your own
Each atom that exists can form a certain number of bonds with another atom. Anything in group 1 of the periodic table can form 1 bond, group 2 can form 2 bonds, group 3 can form 3 bonds, group 4 can form 4 bonds, group 5 can form 3 bonds, groups 6 can form 2 bonds & groups 7 can form 1 bond. Use this information to colour code your periodic table (e.g. anything that forms 1 bond colour red etc). Task: Try & work out the formulae for the following compounds, based on the number of hands the atom has. Draw out each compound.
