We’re being asked to give the chemical formula of the following combinations

a) rubidium and bromine

b) sulfur and barium

c) calcium and fluorine.

The rules for naming binary ionic compounds are as follows:

1. The metal keeps its name and is named and written first.

– For transition metals, we use Roman numerals to denote its charge.

2. The nonmetal keeps its base name but has its ending changed to –ide.
