Dear Student,

 

Atomic number of nitrogen is 7.

Ground state iE.C. of N = 1s², 2s²,2p³.

Example of ammonia formation: When hydrogen atoms approach to nitrogen during the formation of ammonia, one 2s orbital and three 2p orbitals of nitrogen combine to form four hybrid orbitals having equivalent energy which is then considered as an sp³ type of hybridization. Thus, while formation of any molecule formation, all second energy level suborbitals of nitrogen present in the ground state combine together to form hybrid orbitals in its excited state.
