Question

The total energy of electron in ground state of hydrogen atom is _13.6 ev

Answer 1

Solution :

Total energy E=−13.6evE=−13.6ev

K.E=−E=13.6evK.E=−E=13.6ev

P.E=−2K.E=−2×13.6P.E=−2K.E=−2×13.6

=−27.2ev

hope this answer helpful u

Answer 2

The total energy of electron in ground state of hydrogen atom is -13.6ev
