Question

How much energy is required to raise a hydrogen atom from the ground state to the second excited state?

विकल्प

• \[E_{3}-E_{1}=1.51\,\mathrm{eV}\]

• \[E_{3}-E_{1}=10.2\,\mathrm{eV}\]

• \[E_{3}-E_{1}=12.09\,\mathrm{eV}\]

• \[E_{3}-E_{1}=13.6\,\mathrm{eV}\]

Answer 1

The second excited state is the third orbit. The required energy is \[E_{3}-E_{1}=(-1.51)-(-13.6)=12.09\,\mathrm{eV}\].
