The formation of lithium fluoride (seen here) is due to a) a stronger pull by the lithium atom on its valence electron. b) increased stability in the completion of fluorine's outer shell. c) the addition of an outer (higher) energy level in the fluoride ion. d) decreased attraction between the lithium and fluoride ions.

The correct answer is option B) greater stability in the termination of the outer fluorine layer

Explanation:

Hello! Let's solve this!

In the formation of lithium fluoride, lithium gives up its electron to stabilize the last layer of the fluorine, which in turn accepts that electron.

The compound is a neutral salt.

The correct answer is option B) greater stability in the termination of the outer fluorine layer.
