The hydrogen-like species Li^"2+" is in a spherically symmetric state

1.	The hydrogen-like species Li^"2+" is in a spherically symmetric state S_1 with one radial node. Upon absorbing light the ion undergoes transition to a state S_2. The state S_2 has one radial node and its energyis equal to the ground state energyof the hydrogen atom. Energy of the state S_1 in units of the hydrogen atom ground state energy is
Answer» `4.50` `1.50` `2.25` `0.75` SOLUTION :ENERGY of STATE `S_1 =-13.6(3^2/2^2)` eV/atom =`9/4` (energy of H-atom in GROUND state) 2.25 (energy of H-atom in ground state )
