Question

is energy conserved when an atom emits a photon of light? explain

Answer 1

Hey frnd

There is always a energy conservation when an emit photon. When a electron jump From higher state to lower​ energy
it emit energy. And this energy appear in form of photon of light.
Hope this helps...

Answer 2

Answer:

Yes, energy is conserved when an atom emits a photon of light.

Explanation:

An electron jumps down from a higher energy orbital to a lower energy orbital by loosing it's energy. This energy is emitted out of an electron as photons.

Photons are quantum particles. They are very small packets of energy or electromagnetic radiation also known as light quantum. It is called light quantum because is the basic unit of light.

According to the law of conservation of energy:

"Energy can neither be created nor destroyed in an isolated system. It can only be converted from one form of energy to another."

Therefore, energy emitted by electrons as photons in an isolated system is always conserved.
