Question

An excited hydrogen atom emits light when its electronGroup of answer choicesmakes a transition to a lower energy level,is excited to a higher energy level,is in the ground statenone of the above

Answer 1

Step-by-step explanation:

When energy is provided to the hydrogen atom, the electron in the atom goes to a higher excited state or higher energy level by absorbing some of the incident energy. When this electron makes the transition from the higher energy level to the lower energy level, it emits the energy in the form of electromagnetic radiation which is equal to the energy difference between the two energy levels between which the electron makes the transition. The amount of energy emitted is equal to the amount of energy absorbe by the electron.

Thus, an excited hydrogen atom emits light, when its electron makes the transition to a lower energy level.

Final answer:

An excited hydrogen atom emits light when its electron makes the transition to a lower energy level.
