Question

Obtain an expression for total energy of electron in first orbit of
doubly ionised lithium atom how do these values compare with the
corresponding value of hydrogen atom

Dear Student,general expression for the total energy En=-Z2n213
6eVfor Z=3,n=1E=-13 6*9=-122 4 eV
for hydrogen Z=1,n=1E=-13 6 eV Regards
