nitrogen family

How many of the following properties increase down the group for nitrogen family (a) Atomic size (b) Acidic character of oxides (c) Boiling point of hydrides (d) Reducing power of hydrides (e) Extent of p pi - p pi overlap (f) Metallic character (g) Basic character of hydrides

Given below are some properties. How many of these can hold good for phosphorous (a) Metal (b) Non- metal (c) Metalloid (d) Exhibits allotropy (e) Catenation property (f) Solid (g) Good conductor of electricity (h) Least dense among nitrogen family elements

Assertion (A) : The atomic radil of the electrons of oxygen family are smaller than the atomic radil of corresponding electrons of the nitrogen family Reason (R ) : The members of oxygen family are all more electromagative and thus have lower value of nuclear tahn those of the nitrogen famoly
