Vedclass · Answer

(B) The total energy of an electron in an atom is given by the expression $E_n = -\frac{13.6 \ Z^2}{n^2} \ eV$. Since the electron is bound to the nucleus by electrostatic forces of attraction,the potential energy is negative and its magnitude is greater than the kinetic energy. Therefore,the total energy (sum of kinetic and potential energy) is always negative,indicating that the electron is in a bound state.
