Which of the following statements are true for an atom with 3energy levels? You can choose more than one answer.
When atomic electrons are excited to a higher level, they alwaysreturn to their lowest energy level by jumping down one level at atime.
For a given battery voltage thekinetic energy of the free electron at the point of collision ishigher if the atom is closer to the source of electrons.
When a free electron hits anatom, the atom is always excited to the highest energy levelpossible.
For a given position of the atom,the kinetic energy of a free electron at the point of collisionincreases as the voltage of the battery increases.
The number of differentwavelengths emitted by the atom depends on the number of freeelectrons passing through the lamp.
The number of differentwavelengths emitted by the atom depends on how much kinetic energythe free electron has when it hits the atom.
Photons are emitted as electronsin the atom jump up in energy.
