Question

An electron with values $4, 2, -2$ and $+1/2$ for the set of four quantum numbers $n,\,\,l,\,\,{{m}_{l}}$ and $s$ respectively, belongs to:

• A. $4s$ orbital
• B. $4p$ orbital
• C. $4d$ orbital
• D. $4f$ orbital

Answer 1

Answer: (C)

$4d$ orbital

Answer 2

$n=4$ (4th Shell) $l =2(d$ -sub shell) $m_{l} =-2(d_{x y}$ orbital ) $s =+\frac{1}{2}(\uparrow) \ldots$ (i) Hence, electron belongs to $4 d$ orbital.
