Electrons in atoms have quantized energy levels.

Vedclass · Answer

(A) The electrons in a gaseous atom exist in specific,discrete energy levels. When an electron transitions from a higher energy level to a lower energy level,it emits energy in the form of a photon with a specific frequency corresponding to the energy difference $(E = h
u)$. Since these energy levels are quantized,the emitted radiation consists of specific,discrete wavelengths,resulting in a line spectrum rather than a continuous one.

The emission spectrum of a gaseous atom is line-based and not continuous. Why?
