Question

Which of these electron transitions correspond to absorption of energy and which to emission?

Answer 1

The energy will be absorbed for the electron transitions n= 3 to n= 4.

There are two ways in which electrons can transition between energy levels:

1. Absorption spectra: This type of spectra is seen when an electron jumps from a lower energy level to a higher energy level. In this process, energy is absorbed.
2. Emission spectra: This type of spectra is seen when an electron jumps from a higher energy level to a lower energy level. In this process, energy is released in the form of photons.

for n=3 to n=4,  the equation used to calculate the energy of transition is,

$E = - 2.178$×$10$⁻¹⁸$J ($ $1 / n$$i$² $- 1/nf$ ²$)$

Thus, for n = 3 to n = 4, as the electron is getting jumped from lower energy level (n = 3) to higher energy level (n = 4), the energy will be absorbed.
