Solution

(A) (i) Hydronium ion
(ii) Ammonium ion
(B) Magnesium is a metal with elecronic configuration of 2, 8, 2 and it tends to lose its 2 outer-shell valence electrons to become a magnesium ion (2, 8).
The two electrons lost by the magnesium is gained by the two chlorine atoms (2, 7) and thus produce magnesium ion and two chloride ions.
