When an electron moves from one energy level to another, if the transition is to a energy level, energy is absorbed, and a photon is by the atom. Question 16 options:
higher; absorbed
lower; emitted
lower; absorbed
higher; emitted

Explanation:

The atom absorbs or emits light in discrete packets called photons, and each photon has a definite energy. Only a photon with an energy of exactly 10.2 eV can be absorbed or emitted when the electron jumps between the n = 1 and n = 2 energy levels.
