P- block elements ( 15 group elements) General properties of p block elements are: 1, p- block elements are placed in groups 13 to 18 of periodic table. 2, General electronic configuration is ns2 np1-6 3, The presence of all three elements: metals, non metals and metalloids present in p- block Group 15 elements Members :: Nitrogen, Phosphorus, Arsenic, Antimony and Bismuth.. Electronic configuration: ns2 np3 Atomic radii: Increased from N to p. But As to Bi show a slightly increase in atomic radii due to the presence of d and / or f - orbits Ionisation enthalpy: Decreases with increase in atomic number Electronegativity:Decrease down in the group with increase in atomic size Chemical properties : Common oxidation states: -3, +3, and +5 Nitrogen oxidation states: +1, +2, +4 Phosphorus oxidation states :: +1 and +4
