For hydrogen atom, energy of an electron in first excited state is -3.4 eV, K.E. of the same electron of hydrogen atom is . Value of is _________ (Nearest integer) [2024]
(34) For an electron present in a single electron species in any of the orbits,
Total energy : kinetic energy : potential energy = -1 : +1 : -2
Thus if total energy is -3.4 eV, then kinetic energy is +3.4 eV = eV.
