# What happens when two nitrogen atoms share electrons?

The isolated nitrogen ATOM has 5 valence electrons. When 2 such atoms bind 3 electrons from each centre overlap to form a region of high electron density between and around the nuclei, which we conceive as $: N \equiv N :$ a nitrogen-nitrogen triple bond, the strongest chemical bond. The remaining 2 electrons on each centre are conceived to be lone, non-bonding pairs
