Question

Given the ionic formula below, what is the charge on ion X? Be sure to

Answer 1

Answer:

Charge on X  = (+ 2)

Explanation:

Charge on one Cl = -1

So Charge on two Cl = -2

The molecule = Neutral = 0 charge

So, to make total charge = 0 , the X should have +2 charge

XCl2 = +2 -2 = 0

X = +2

Alkaline earth metals(Be , Mg , Ca , Sr) form such type of compounds.

Example :

$MgCl_{2}$

$CaCl_{2}$
