The electron transitions representing absorption of energy are:
(a) n = 2 to n = 4
(d) n = 3 to n = 4
and those which represents emissions of energy are:
(b) n = 3 to n = 1
(c) n = 5 to n = 2
An electron emits energy when it jumps from a higher energy level to a lower energy level transitions.
An electron absorbs energy to jump from a lower energy level to a higher energy level transitions.
(a) n = 2 to n = 4
Here, the initial level (2) is lower than the final level (4).
Hence energy is absorbed.
(b) n = 3 to n = 1
Here, the initial level (3) is higher than the final level (1).
Hence energy is released.
(c) n = 5 to n = 2
Here, the initial level (5) is higher than the final level (2).
Hence energy is released.
(d) n = 3 to n = 4
Here, the initial level (3) is lower than the final level (4).
Hence energy is absorbed.
