Question

The total energy of electron in the ground state of
hydrogen atom is -13.6 eV. The kinetic energy of an
electron in the first excited state is
​

Answer 1

Answer:

(a) The quoted value of E = – 3.4 eV is based on the customary choice of zero of potential energy at infinity. From the above result of E = – Ek, the kinetic energy of electron in this state is + 3.4 eV.
