Answer
Magnesium loses its two valence electrons to acquire a stable octet. The two chlorine atoms accept one each of these electrons to acquire a stable octet. Thus, electrovalent bond in MgCl2 is formed by transfer of electrons.
When a molecule of CCl4 is to be formed, one atom of carbon shares four electron pairs, one with each of the four atoms of chlorine. Thus, covalent bond is formed by sharing of electrons.
