Question

Which of the following statements are true for an atom with 3 energy levels? Choose more than one answer.

A. The number of different wavelengths emitted by the atom depends on how much kinetic energy the free electron has when it hits the atom.

B. For a given position of the atom, the kinetic energy of a free electron at the point of collision increases as the voltage of the battery increases.

C. When a free electron hits an atom, the atom is always excited to the highest energy level possible.

D. Photons are emitted as electrons in the atom jump up in energy.

E. The number of different wavelengths emitted by the atom depends on the number of free electrons passing through the lamp.

F. For a given battery voltage the kinetic energy of the free electron at the point of collision is higher if the atom is closer to the source of electrons.

G. When atomic electrons are excited to a higher level, they always return to their lowest energy level by jumping down one level at a time.
