Magnesium fluoride contains only magnesium and fluorine. what is the formula for this compound? express your answer as a chemical formula

Explanation:

Atomic number of magnesium is 12 and its electronic configuration is 2, 8, 2. So, to acquire stability it loses 2 valence electrons and hence forms ion.

Whereas atomic number of fluorine is 9 and its electronic distribution is 2, 7. And, to attain stability its needs to gain one electron and hence then it forms ion.

Therefore, when both magnesium and fluorine chemically combine together then magnesium atom will donate its 2 valence electrons to the fluorine atom.

Hence, they will tend to form magnesium fluoride, that is, .
