Mercury emits the blue, green and yellow frequency of light.

Question 2

List Bohr’s main ideas.

Answer 2

Electrons move in a circular orbit.
The electrostatic force of attraction keeps electrons moving.
Electrons occupy the lowest energy orbit available.
Electrons can jump to a higher energy level by absorbing some energy.
Electromagnetic radiation is emitted by an excited atom when an electron falls from a higher energy level.
