1.	A hydrogen atom and a `Li^(2+)` ion are both in the second excited state. If `l_H` and `l_(Li)` are their respective electronic angular momenta, and `E_H and E_(Li)` their respective energies, then (a) `l_H gt l_(Li) and \|E_H\| gt \|E_(Li)\|` (b) `l_H = l_(Li) and \|E_H\| lt \|E_(Li)\|` (C ) `l_H = l_(Li) and \|E_H\| gt \|E_(Li)\|` (d) `l_H lt l_(Li) and \|E_H\| lt\|E_(Li)\|`
Answer» Correct Answer - B in second excited state n=3 So, `l_H = l_(Li) = 3((h)/(2pi))` while `E prop Z^2 and Z_H = 1, Z_(Li) = 3` So, `\|E_(Li)\| = 9\| E_H\|` or `\|E_H\|lt\|E_(Li)\|.`
