Explanation :

New combination and predicted formula of given compounds are shown below in image.

Ionic compounds are the ones which are formed when metal and non-metal combines in their ionic form.

For the formation of compound, all charges on the metal and non-metal should be balanced.

Like, we take an example of compound \(CaBr_{2}\), in this the +2 charge of Ca is balanced by the 2\(Br^{-}\) ions.
