The energy required to knock out the electron in the third orbit of a hydrogen atom is equal to |
$13.6 eV$ $+\frac{13.6}{9} eV$ $-\frac{13.6}{3} eV$ $-\frac{3}{13.6} eV$ |
$+\frac{13.6}{9} eV$ |
Energy required to knock out the electron in the nth orbit $=+\frac{13.6}{n^2} eV \Rightarrow$ $E_3=+\frac{13.6}{9} eV$ |
