Predict the formulae of the stable binary compounds that would be formed by the following pairs of elements:
calcium and iodine

Solution

Calcium belongs to group 2 with a valence of 2. Iodine being halogen belongs to group 17 with a valence of 1. Hence the formula of the compound formed would be CaI₂.
