What is energy quantization in atoms?
0:02
Definition: Energy quantization in atoms
0:05
means that electrons can only occupy
0:08
certain fixed energy levels around the
0:10
nucleus, not values in between.
0:13
Explanation: In the quantum model of the
0:15
atom, electrons don't move in random
0:18
paths, but exist in discrete energy
0:20
states. When an electron jumps between
0:23
these states, it absorbs or emits energy
0:26
as a photon. The difference in energy
0:29
between levels determines the wavelength
0:32
color of the light. This explains atomic
0:34
line spectra. Lower levels equals more
0:37
stable, closer to the nucleus. Higher
0:40
levels equals less stable, farther from
0:43
the nucleus. Electrons must quantum jump
0:46
between levels. No half steps are
