Question

What is the charge of magnesium ion in $Mg{Cl}_2$?

• A. +1
• B. +3
• C. +2
• D. +4

Answer 1

The correct option is C

+2

Magnesium will loose 2 electrons to attain stability and clorine will need an electron to attain stability. Since, we know charge on cholrine is -1 (as it gains electrons) and magnesium can give 2 electrons forming a compund MgCl₂.​ Thus, the charge should be +2.​
