Nitrogen energy-level diagram

Draw simple molecular orbital energy-level diagrams to indicate how the bonding in the saline hydrides, such as NaH or KH, differs from that between hydrogen and a light p-block element such as carbon or nitrogen.

Hund s rule states that the electrons within a given subshell remain as unpaired as possible. Moreover, if there are two or more unpaired electrons in a given subshell, they all must occupy different orbitals and have the same electron spin (all arrows representing unpaired electrons in a subshell point up or all point down). The energy level diagrams for the carbon, nitrogen, and oxygen atoms illustrate these rules ... 

A typical energy level diagram of inner n and n molecular orbitals of the bent azo group, N—N, in the ground state is shown in Fig. 2,a (41). Here, a 7t molecular orbital containing two electrons, as well as a vacant n orbital, result from the interaction of pz nitrogen atomic orbitals not involved in the sp2 hybridization of the N atoms. On the other hand, the n and n + molecular orbitals, each filled with two electrons, arise from interaction of sp2 nitrogen...
