Question

nitrogen contain 5 electron in its valence shell at its maximum valency is 4 why​

Answer 1

nitrogen don't show their valency in ground state. so it go in exicted state so they show maximum vaency 4

Answer 2

Answer:

Nitrogen has atomic number 7. The number of valence electrons=5 so the maximum valency=5. . Nitrogen can form 3 covalent bonds and also it can form a fourth bond with other atom due to the presence of lone pair so its maximum covalency will be 4.
