WebbThe number of unpaired electrons in the last orbit of an element is the valency of that element. As we know, the correct electron configuration of nitrogen in ground state will be 1s 2 2s 2 2p x1 2p y1 2p z1. Here, the nitrogen atom has three unpaired electrons. Therefore, the valency of nitrogen is 3. WebbNitrogen, även kallat kväve, är ett grundämne med det kemiska tecknet N, som utgör 78 % av jordens atmosfär. Nitrogen ingår i naturens kretslopp och är nödvändigt för allt liv på jorden, bland annat som en viktig beståndsdel i proteiner och DNA. Fritt nitrogen består av tvåatomiga molekyler och har därför den kemiska beteckningen N2. EGENSKAPER
