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. Q. The state S_(1) is:

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. Q. The state S_(1) is:
Answer» 1s 2S 2p 3s Solution :2s is SYMMETRICAL havig one RADIAL node.
