MCQ

The energy required to release $ 1$ electron from $H{e^ + }$ is ............ $\mathrm{eV}$

A
$+ 54.4$
✓
$-13.6$
C
$+ 27.2$
D
Cannot be predicted

✓

Answer

Correct option: B.

$-13.6$

b
(b)$E = - \frac{{13.6}}{{{n^2}}}\,\,for\,\,H{e^ + }\,\,n = 1$

$E = - \frac{{13.6}}{{{1^2}}} = - 13.6\,eV$.
