Question 1

Bohr’s theory

Answer 1

• A photon of light is emitted or absorbed when the electron changes enegy levels
• The energy of a photon equals the difference between the two energy levels

Energy of a photon E (J) = Planck constant h (Js^-1) x Frenqucy v (s^-1)

Question 2

Lyman’s series

Answer 2

• The ring represents the energy levels of electron
• The further away from the nucleus an electron is, the higher the energy level
