Charateristic which delimit a family are more general than those which delimit a

Statement-1: The atomic radii of the elements of the oxygen family are smaller than the atomic radii of the corresponding elements of the nitrogen family. Statement-2: The members of the oxygen family are more electronegative and thus have lower values of nuclear charge than those of the nitrogen family.

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

Assertion: The atomic radii of the elements of the oxygen family are smaller than the atomic radii of corresponding elements of the nitrogen family. Reason: The members of the oxygen family are more electronegative because they have lower values of nuclear charge, than those of the nitrogen family.
