Energy of an electron in hydrogen atom in ground state is -13.6 eV.
En= -Z² 13.6 / n² electron volt----------1
Energy levels higher than ground energy state in an atom is called as excited energy state/ level.
Energy of electron in second excited state means :
Z=1, n=3
On substituting these values in equation 1 we get .
En=- (1)²x 13.6/3² electron volt
En=- 1x 13.6/9
En=-1.5 electron volt.
∴Energy of the electron in the second excited state in hydrogen atom is -1.5 electron volt.
