If the ionisation energy for the hydrogen atom is 13.6 eV , then the energy required to excite it from the ground state to the next higher state is nearly
10.2 eV
13.6 eV
-10.2 eV
-3.4 eV
Solution
Minimum energy required to excite from ground state,
$\mathrm{E}_{\min }=13.6\left[\frac{1}{1^2}-\frac{1}{2^2}\right]=10.2 \mathrm{eV}$
