Modified shell model of nitrogen gas (N₂): Description: Each nitrogen has 5 valence electrons. The two nitrogen atoms share 3 pairs of electrons (a triple bond). Each atom ends up with a full outer shell (8 electrons). You’d show two N atoms with 3 shared pairs between them and 2 lone pairs on each N. Dot diagram model of nitrogen gas (N₂): Description: Two N atoms connected by three lines (or 3 pairs of dots) to show a triple bond. Each N also has one lone pair (two dots) outside the bond.
