The electron in any hydrogen atom jump on absorbing 12.75 eV of energy would jump to.......orbit.

Step-by-step solution

The transition energy for hydrogen atom is given by, E=-R [ 1 n₂^2 - 1 n₁^2 ] When R=13.6 eV , n₁=1, n₂= ? Given, E=12.75 eV 12.75=-13.6 [ 1 n₂^2 - 1 1^2 ]-0.9375= 1 n₂^2 -1 aligned & 1 n₂^2 =-0.9375+1 & n₂^2=16 & n₂=4 aligned
