Answer 2

Electro-valency of fluorine in magnesium fluoride is 1.

• The chemical formula of the the magnesium fluoride is MgF2.
• Now, the electronic configuration of fluorine is 2,7
• So, a fluorine atom will need one electron to complete it's octet.
• Same, things happen in this case also. The two fluorine atoms take 1 electron (total 2) from the magnesium atom and forms the sodium fluoride compound.

[Mg]+² + 2×[Cl]-¹ = MgCl

• The electro-valency of each of the fluorine atoms in the magnesium fluoride is 1.
