Q. An electron with values $4,\ 3,\ - 2$ and $+ \frac{1}{2}$ for the set of four quantum numbers $n,\ l,\ m_{1}\ and\ m_{s}$, respectively, belongs to
A) $4s$ orbital
B) $4p$ orbital
C) $4d$ orbital
D) $4f\$orbital
Explanation
(d)
The value of ‘$n$’ and ‘$l$’ equal to 4 and 3 respectively corresponds to 4$f$-orbital, hence the electron will belong to 4$f$-orbital.
