Question

The ground state energy of the hydrogen atom is -13.6 eV. The kinetic and potential energy of the electron in the second excited state is respectively ______ 

विकल्प

• +3.02 eV, +1.51 eV

• +3.02 eV, -1.51 eV

• -1.51 eV, +3.02 eV

• 1.51 eV, -3.02 eV

Answer 1

The ground state energy of the hydrogen atom is -13.6 eV. The kinetic and potential energy of the electron in the second excited state is respectively 1.51 eV, -3.02 eV.

Explanation:

For second excited state n = 3

The total energy in the third orbit

`E_3 = (-13.6)/9`eV = -1.51 eV

K.E. = -T.E. = 1.51 eV

P.E. = 2.T.E. = -3.32 eV
