Using the periodic table predicts the formulae of compounds which might be formed by the following pairs of elements:

(a) Silicon and bromine.

(b) Aluminium and sulphur.

Solution

(a) Silicon belongs to group 14 with a valence of 4. Bromine being halogen belongs to group 17 with a valence of 1. Hence the formula of the compound formed would be SiBr₄.
(b) Aluminium is group 13 element with a valence of 3. Sulphur belongs to group 16 elements with a valence of 1. Hence the formula of the compound formed would be Al₂S_3.
