Text Solution

Verified by Experts

The correct Answer is:
B
`IV^(th)` member will be in 5th period.
`therefore` Atomic number `=overset"II"7+overset"III"8+overset"IV"18+overset"V"18 =51`

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

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.
