Question

When magnesium (Mg2+) and fluorine (F1-) combine in an ionic bond, the resulting formula will be
Responses
A Mg2F.Mg 2 F.
B Mg2F2.Mg 2 F 2 .
C MgF.MgF.
D MgF2.

Answer 1

When magnesium (Mg²⁺) and fluorine (F⁻) combine in an ionic bond, the magnesium ion has a charge of +2, and each fluorine ion has a charge of -1. To balance the charges, one magnesium ion will need two fluorine ions, resulting in the formula:

**D. MgF₂.**

So the correct answer is D. MgF₂.
