Describe what is shown in each picture.
A
Absorption: Energy is absorbed by an atom. When the energy is absorbed, an electron moves from close to the nucleus to far from the nucleus.
Describe what is shown in each picture.
B
Emission: Energy is released by an atom. An electron moves from far from the nucleus to close to the nucleus. This causes energy to be released.
