Answer:
We know based on the charges of each ion and the fact that they must always sum to 0
Explanation:
Na only has one outer electon to give so it is always +1
Mg has two outer electrons so it always gets +2
Halogens have one "missing" electron in their outer shell so they get a -1
For NaCl (+1) + (-1) = 0
For MgI2 (+2) + 2(-1) = 0

The answer is E. Cl -- Cl
Chloride, Cl2, has a non-polar covalent bond because both molecules making up the compound are identical. This results to a diatomic molecule, which are known non-polar molecules. Since both sides of the bond are also the same, there is equal sharing of electrons. Polar covalent bonds are those that have unequal sharing of electrons.
