The potential energy of electron revolving in the ground state of H atom is — Atomic Structure Chemistry Question

💡 Solution & Explanation

The total energy E in the ground state of a hydrogen atom (n = 1, Z = 1) is -13.6 eV. By the virial theorem, Potential Energy P.E. is equal to twice the total energy: P.E. = 2 * E = 2 * (-13.6 eV) = -27.2 eV.
