Best Answers

Valency of any atom is the maximum number of valence electrons that can be shared by the concerned atom . Now , electronic configuration of Nitrogen is 1s2 2s2 2p3 . As , observed , valence shell contain 5 electrons , so maximum valency of Nitrogen can be 5 . read more

In ammonia valency of nitrogen is -3 as valency of hydrogen in all compounds other than metallic compounds is +1 ( In metallic compounds as metallic elements have positive valency like +1, +2 etc. the valency of hydrogen in such compounds is -1). read more
