Question

Energy of an electron in hydrogen atom in ground state is -13.6 eV. What is the energy of the electron in the third excited state? ​

Answer 1

Given:

Total energy of electron E=−3.4eV

The Potential energy of the electron is given by:

U=2E

U=2×(−3.4 eV)

⇒ U=−6.8eV

Answer 2

Answer:

0.85 eV is the energy of the electron in third excited state
