Question

Magnesium has an atomic number of 12.What is the most stable charge for a magnesium ion?
A)a +1 charge
B)a +2 charge
C)a -1 charge
D)a -2 charge

Accepted Answer

Magnesium has two valence electrons and it tends to lose both electrons to achieve a stable octet configuration. This results in the formation of a +2 ion, which is the most stable charge for a magnesium ion.
