Solution
As per the virial theorem, the potential energy is twice as large as the kinetic energy. It means
- P.E = 2K.E
Total energy = K.E + P.E
Total energy = K.E - 2K.E
Total energy = -K.E
OR , Total energy = P.E / 2
Therefore, K.E = 54.4 eV
Potential energy = - 2*54.4
Potential energy = -108.8 eV
Ionization potential is the energy required to remove an electron from the ground state. For He + ion, Ionization potential is equal to 54.4 eV
