Ions (ionic bonding) and the sharing of electrons (covalent bonding) were introduced as a means of chemical bonding. Also covered was metallic bonding, featuring metals in groups 3-12.
The students were reminded of Polyatomic Ions, and how to spot them in a chemical formula.
They were asked to spot the polyatomic ions and count the number of atoms per formula in the worksheet below:
