Question

What is the energy of the electron in the first orbit of a hydrogen atom?

विकल्प

• \[E_{1}=0\,\mathrm{eV}\]

• \[E_{1}=-13.6\,\mathrm{eV}\]

• \[E_{1}=-3.40\,\mathrm{eV}\]

• \[E_{1}=-1.51\,\mathrm{eV}\]

Answer 1

The first orbit is the ground state of hydrogen. The electron's energy in this orbit is \[E_{1}=-13.6\,\mathrm{eV}\].
