What does the chemical formula cacl2 show about the compound it represents? the person who answered this question first was wrong! the answer is: it is made up of two elements.

Explanation:

A compound formed by transfer of electrons from one atom to another is known as ionic compound. And, bond formed due to transfer to this type of transfer is known as ionic bond.

Therefore, is an ionic compound as it is formed by transfer of electrons from calcium to chlorine atoms.

This compound is formed by chemical combination of one calcium and two chlorine atoms.

This means basically, is made up of two elements which are calcium and chlorine.

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)
