The only e^- in the H-atom resides under ordinary conditions on the first orbit when energy is supplied, the e^- moves to higher energy shells depending upon the amount of energy absorbed. When an e emits energy i.e., the e^- returns to the lowest energy state, from this Lyman, Balmer, Paschen, Bracket, Pfund series are there, so different spectral lines in the spectra of atoms correspond to different transitions of e^- s from higher to lower energy levels: In an hydrogen atom which of the following transition should be associated with highest absorption of energy

Answer»

n = 1 to n = 4
n = 2 to n = 3
n = 4 to n = 1
n = 3 to n = 2

SOLUTION :Energy is absorbed when the transition is from LOWER level to UPPER level.
