Molecular orbitals: N2
The animation below shows the bonding interaction of nitrogen 2pz orbitals on two nitrogen atoms as they approach. The two dots represent the N nuclei.
The σpz-bond in dinitrogen (N2).
The bonding interaction of nitrogen 2pz orbitals on two nitrogen atoms as they approach..
Note that more advanced treatments of the bonding show that this orbital is not a pure 2pz + -2pz combination; instead there is also some 2s character as well.
