If $13.6 eV$ energy is required to lionize the hydrogen atom, then the energy required to remove an electron from $n = 2$ is :

Options:

Answer:

Solution:

The energy required to remove an electron from $n^{th}$ orbit is $n$

$E_{n} = - \frac{13.6}{n^{2}}$

Here $n = 2$

Therefore $E_{2} = - \frac{13.6}{2^{2}}$
$= - 3.4 eV$
