Which of the following atoms has minimum covalent radius

A
$B$
B
$C$
✓
$N$
D
$Si$

✓

Answer

Correct option: C.

$N$

c
As we move along a period radius decreases and as we move down the group, radius increases.

Hence, $B (5)\,>\, C (6)\,>\, N (7)$.

Also, $\left( r ^{ n } \propto \frac{1}{Z}\right.$ along a period)
