MCQ
Angular momenutum of electron in $M$ -shell of $Li^{+2}$ ion is
- A$1.054 \times 10^{-27} \,erg. s$
- B$1.99 \times 10^{-19} \,erg. s$
- ✓$3.162 \times 10^{-27} \,erg. s$
- D$9.486 \times 10^{-27} \,erg. s$
$=n \frac{h}{2 \pi}=\frac{3 \times 6.62 \times 10^{-34} \times 10^{7}}{2 \times 3.14}$
$=3.162 \times 10^{-27}$ $ergs$
