JEE MainPhysicsAtoms and NucleiMCQ+4 / −1
A hydrogen atom makes a transition from n = 2 to n = 1 and emits a photon. This photon strikes a doubly ionized lithium atom (z = 3) in excited state and completely removes the orbiting electron. The least quantum number for the excited state of the ion for the process is :
  1. A
    2
  2. B
    3
  3. C
