Energy, Light, Electrons and Photons

Front

What is the excited state of an electron?

Back

The excited state of an electron occurs when it is in a higher energy level, further from the nucleus, and is unstable.

Front

What happens when an electron moves from n=4 to n=2?

Back

The electron releases energy.

Front

What occurs when an electron returns to the ground state from an excited state?

Back

The atom emits energy.

Front

How does light emission from an atom occur?

Back

Light is emitted when an electron drops from a higher to a lower energy level.

Front

What is visible light?

Back

Visible light is the light that can be seen by the human eye.

Front

What is the ground state of an electron?

Back

The ground state is the lowest energy state of an electron, where it is closest to the nucleus.

Front

What is the relationship between energy levels and electron stability?

Back

Electrons in higher energy levels are less stable than those in lower energy levels.

Front

What is the process of absorption in terms of electron energy levels?

Back

Absorption occurs when an electron moves from a lower energy level to a higher energy level, gaining energy.

Front

What type of light is ultraviolet light?

Back

Ultraviolet light is a type of electromagnetic radiation with a wavelength shorter than visible light but longer than X-rays.

Front

What is the significance of the valence state of an electron?

Back

The valence state refers to the outermost electrons that determine an atom's chemical properties and bonding behavior.
