So suppose I have two fluorine atoms. So I take these two fluorine atoms, so two of them, and they interact with one another to form a diatomic fluoride. Now, what that basically means is that two of these guys will orient in a way such that these two single electrons will interact and they will form a cobaltin bond in which there is a sharing of electrons. So that means this electron will be donated to this orbital, and this electron will be donated to this orbital. So two fluoride will interact to form an electron configuration of the nearest noble gas. The nearest noble gas is neon.
