Q. When a hydrogen atom is bombared, the atom is excited to then $n = 4$ state. The energy released, when the atom goes from $n = 4$ state to the ground state is

A) 1.275 eV
B) 12.75 eV
C) 5 eV
D) 8 eV
Explanation

(b) Energy released $= E_{4} - E_{1}$
$= - \frac{13.6}{4^{2}} - \left( - \frac{13.6}{1^{2}} \right) = 1.75eV$
