Match the correct atomic radius with the element:
Element Atomic radius (pm)
(a) $B e$ (p) $74$
(b) $C$ (q) $88$
(c) $O$ (r) $111$
(d) $B$ (s) $77$
(e) $N$ (t) $66$

Solution

Atomic radius decreases from left to right within a period. This is caused by the increase in the effective nuclear charge.

$B e > B > C > N > O$

$a . B e ⟶ 111 (r)$

$b . C ⟶ 77 (s)$

$c . O ⟶ 66 (t)$

$d . B ⟶ 88 (q)$

$e . N ⟶ 74 (p)$
