Question #471a4

Answer 1

Electrons have set orbits around the nucleus, whose energies depend on size. When an electron moves between orbits radiation is either absorbed or emitted.

Explanation:

"

• Electrons orbit the nucleus in orbits that have a set size and energy.
• The energy of the orbit is related to its size. The lowest energy is found in the smallest orbit.
• Radiation is absorbed or emitted when an electron moves from one orbit to another.
