Energy, Light, Electrons and Photons

Front

What happens when an electron returns to ground state from an excited state?

Back

The atom will emit energy.

Front

What do we call electrons that are found in lower energy levels and are in a stable orientation?

Back

These electrons are in the ground state.

Front

What causes a line emission spectrum?

Back

It happens when an electron transitions from a higher to a lower energy level.

Front

What is the light that is visible to the human eye called?

Back

Visible light.

Front

Where are valence electrons located in an atom?

Back

On the outermost energy level in an atom.

Front

What is the definition of energy levels in an atom?

Back

Energy levels are the fixed distances from the nucleus where electrons can be found.

Front

What is the difference between ground state and excited state?

Back

Ground state is when electrons are in the lowest energy levels, while excited state is when electrons have absorbed energy and moved to higher energy levels.

Front

What is a photon?

Back

A photon is a particle of light that carries energy.

Front

How does light behave as both a wave and a particle?

Back

Light exhibits wave-like properties (such as interference and diffraction) and particle-like properties (such as being made of photons).

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including visible light, ultraviolet light, and infrared light.
