Question

In a hydrogen atom if the energy of electron in the ground state
is-xeV then in 2nd excited state of He+ is

Kumar Kanishk · Answer

Egroun = -x eV
Z of He = 2
n = 3 (since it is 2nd excited state)
En = Eground Z2/n2
= -x 4/9
= -4x/9 eV

In a hydrogen atom if the energy of electron in the ground state is-xeV then in 2nd excited state of He+ is
