Describe how light is emitted from an atom. A) As protons absorb energy they travel from the nucleus through the atom emitting light along the way. B) The light is emitted when energy from sunlight is absorbed by the atom to excite a neutron into a higher level. C) When the nucleus absorbs sunlight, photons are energized and move to a higher energy level and are then released. D) Light is emitted from an atom as an electron falls from an excited state to the ground state releasing a photon.

Answer is: D) Light is emitted from an atom as an electron falls from an excited state to the ground state releasing a photon.

Electrons can jump from one energy level to another, absorbing or emitting electromagnetic radiation with a frequency ν (energy difference of the levels).

When electron jump from higher to lower energy level (shell), it emitting (releasing) energy.

For example, when the electron changes from n=4 (fouth shell) to n=2 (second shell), the photons are emitted.

Answer: Option D

Explanation:

The light is the visible spectrum which is seen by naked eyes. This can be a white light or some other color.

When energy is supplied to the atom, the electrons absorb energy and it tends to move from a lower energy level to a higher energy level.

When the electrons move from the excited state to the ground state, then it releases energy which is visible in the form of light.

This is how light is emitted from an atom.
