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 energy is equal to the ground state energy of the hydrogen atom Energy of the state S_(1) in units of the hydrogen atom ground state energy is
Answer» 0.75 `1.50` 2.25 `4.50` Solution :Energy in `S_(1)` state (i.e., 2S ORBITAL) of `Li^(2+)` ION `= - (13.6 XX 3^(2))/(2^(2)) = - 13.6 xx 2.25 eV` = 2.25 times of `E_(H)`
