Calcium forms ions with a charge of +2. iodine forms ions with a charge of -1. which of the following would represent an ionic compound composed of calcium and iodide ions? options: cai2 cai ca2i ca2i 2cai cai2

Answer : The correct option is .

Explanation :

Ionic compound : It consist of a metal and non-metal. It is made up of ions that  gains or lose electrons and giving them a net positive and negative charge.

Metals have tendency to lose electrons easily, so they become cation which have a positive charge and non-metal have tendency to gain electrons, so they become anion which have a negative charge.

As we know that the Calcium forms ions with a charge of (+2) and Iodine forms ions with a charge of (-1).

Two iodide ion will require to combine with one calcium ion for a neutral compound.

Therefore, the correct representation of an ionic compound of Calcium and Iodide ions is .
