Question

Which of the following statements are true for an atom with 3 energy levels?

You can choose more than one answer.

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

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

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

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

5. 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.

6. 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.

7. 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.

Explanation / Answer

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

FALSE

It depends on the transition of electron from high energy to low energy

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

FALSE

It depends on the transition of electron from different levels

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

FALSE

Electron not emitted but it is absorbed while it move up.

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

FALSE

Electron will reach to higher excited level not the highest level

5. 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.

TRUE

As voltage increases the KE increases

6. 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.

FALSE

it will Not change due to closeness of atom

7. 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.

FALSE

It is not sure how much level it will go down...it may down to any level of
