PERIOD  1: GENERAL PROPERTIES OF NITROGEN – GROUP V ELEMENTS

Nitrogen and other group VA elements are non-metals and show two common valences of 3 and 5. They are electron acceptors and both form several acidic oxides. They also form similar hydrides and chloride e.g., Nitrogen and phosphorus form N₂O₃ and P₄O₆, N₂O₅ and P₄O₁₀, NH₃, PH₃, NCl₃ and PCl₃
