1.	A hydrogen atom and a `Li^(2+)` ion ae both in the second excited state . If `l_H` and ` l_(li)` are their respective angular momentum in an orbit and `E_H` and ` E_(Li)` are their respective enrgies, then :A. `l_H gtl_(Li)` and `E_H gtE_(Li`B. `l_H gtl_(Li)` and `E_H gtE_(Li`C. `l_H gtl_(Li)` and `E_H gtE_(Li`D. `l_H gtl_(Li)` and `E_H gtE_(Li)`
Answer» Correct Answer - B `E_(2Li^(2+)) = E_(2H) xx Z^2` `:. E_(2Li^(2+)) =E_(2h) xx Z^2` `:. E_(2Li^(2+)) gt E_(2H^+)` `= sqrt (l (l + 1)) h/(2pi)` (`:. L= 0`for both ) `:. l_(H^+)= L_(Li^(2+))`.
