Match the correct atomic radius with the element:
S.No. Element Code Atomic radius (pm)
(i) Be (p) 74
(ii) C (q) 88
(iii) O (r) 111
(iv) B (s) 77
(v) N (t) 66
Show answer and solution
On moving left to right in a period, atomic radii decreases due
to increase in Z_eff and addition of electrons to the same outermost
shell.
