Electron Energy and Light

Front

What color of light has the highest energy?

Back

Violet light has the highest energy.

Front

What happens when an electron drops from an excited state to a ground state?

Back

The electron releases energy in the form of a photon of light.

Front

In which state does an electron have the least amount of energy?

Back

The ground state.

Front

What color of light is produced when an electron makes a long fall?

Back

Violet light, because a long fall means high energy and short wavelength.

Front

Order the following from lowest to highest wavelength: Radio, Green, Yellow, X-ray.

Back

X-ray, Green, Yellow, Radio.

Front

What is the relationship between energy and wavelength of light?

Back

Higher energy light has shorter wavelengths.

Front

Define 'excited state' of an electron.

Back

An excited state is when an electron has absorbed energy and is at a higher energy level than its ground state.

Front

What is a photon?

Back

A photon is a particle of light that carries energy.

Front

How does an electron transition from a ground state to an excited state?

Back

An electron absorbs energy, which allows it to move to a higher energy level.

Front

What is the significance of the ground state in an atom?

Back

The ground state is the lowest energy state of an electron, where it is most stable.
