Question

1. explain how electrons cause the emission of light. in your answer be sure to discuss energy levels and support your explanation with a drawing (4 points).

Explanation:

Electrons in an atom occupy specific energy levels. When an electron absorbs energy, it jumps to a higher - energy level (excited state). Since the excited state is unstable, the electron will return to a lower - energy level. When it does so, it releases energy in the form of a photon of light. The energy of the photon is equal to the energy difference between the two energy levels involved. For the drawing, one can depict an atom with its nucleus and electron shells. Show an electron absorbing energy and moving to a higher shell, and then returning to a lower shell and emitting a photon.

Answer:

Electrons absorb energy and jump to higher energy levels. Then they return to lower levels, emitting photons of light. The energy of the photon is the energy difference between the levels. For the drawing, show an atom with electron shell transitions and photon emission.
