Describe in terms of electrons what happens when magnesium reacts with fluorine to form the ionic
compound magnesium fluoride MgF

Hello, Magnesium and fluorine combine to form an ionic compound.This is because Mg has two valence electrons and it would like to get rid of those two ions to obey the octet rule. Fluorine has seven valence electrons and usually forms the F – ion because it gains one electron to satisfy the octet rule.

Explanation:

This is because Mg has two valence electrons and it would like to get rid of those two ions to obey the octet rule. Fluorine has seven valence electrons and usually forms the F – ion because it gains one electron to satisfy the octet rule.
