there is 1 Mg ion
and 2 chlorine ions

ghazi · Answer

C

ghazi · Answer

the valance electron in magnesium is 2 therefore it forms two covalent bond with chlorine...the one electron left in p makes bond with one each electron of magnesium atom

ghazi · Answer

electronic configuration of outer most shell of  Mg : $$3s^2$$ and that of chlorine : $$3s^2 3p^5$$ so one electron in chlorine is left to make bond with Mg atom....

r u sure ghazi - my chemistry is pretty rusty but i thought these were ionic bonds

ghazi · Answer

yes i am 95% sure

turingtest · Answer

which is why this should be in the chemistry section

cwrw238 · Answer

yea - good point Turing1

ghazi · Answer

@cwrw238  agreed you're right....it's an ionic bond...sorry

cwrw238 · Answer

nevertheless I would bet the answer is D
try googling it james - to check the bonding
