Question

atomic and ionic radii of element of this 16 r smaller then group 15 elements give reasons​

Answer 1

Explanation:

in grp 16 we have 1 more proton in the nucleus and shell no remains constant....so binding energy of the nucleus increases....resulting in more attraction of valence shell ....thus grp 16 element atomic radii is smaller than that of grp 15 atomic radii

ionic radii explanation is same too
