1.	The hydrogen -like species `Li^(2+)` is in a spherically symmetric state `S_(1)` with one 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 is to the ground state energy of the hydrogen atom. The orbital angular momentum quantum number of the state `S_(2)` isA. 0.75B. `1.50`C. 2.25D. `4.50`
Answer» Correct Answer - C The energy of `S_(1)`state (for 2s orbital)of `Li^(2+)ion=(-13.6xx(3)^(2))/((2)^(2))=-13.6xx(9)/(4)` `=-13.6xx2.25 eV` `=2.25 ` times of `E_(H)`.
