Atoms from which two elements would form ionic bonds

A metal and a non-metal would exchange electrons with each other and become what is known as an ionic bond. Such as NaCl, Na+ which is a metal ion of the 1a group, and Cl- which is a non metal ion of the 7a group.

So atoms from elements in which there is a metal and a non metal would form an ionic bond.

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this
