In a hydrogen atom if the energy of electron

Asked by admin @ 23/08/2021 in Chemistry viewed by 310 People

in a hydrogen atom,if energy of an electron in groundstate is 13.6eV, then the energy in the 2nd excited state is

Answered by admin @ 23/08/2021

E = 13.6/n^2
for 2nd excited state, value of n = 3
therefore, energy becomes E = 13.6/9 = 1.51eV
