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

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.

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.

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

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.

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

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

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

Expert Solution

TRUE STATEMENTS ARE :

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

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.

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 Statement are:

1.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.

they jump directly to their lowest energy level.

2.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

kinetic energy remains same

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

it depends on the various energy levles of electron they posses.

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

no up but down inenergy level

5) you need the energy levels of a hydrogen atom. A series will be picked and will be asked for the energy for a particular transition. What equation would you use (if there is one) and how would you solve for it? 6) electrons are sent through an electric field and the kinematics are asked. For example is it slows down, how long does it take to stop? If it accelerates, how to find velocity? What equation(s) would you use...

This energy diagram shows the allowed energy levels of an electron in a certain atom

This energy diagram shows the allowed energy levels of an electron in a certain atom. (Note: the SI prefix 'zepto' means 10-21. You can find the meaning of any SI prefix in the ALEKS Data tab.) Use this diagram to complete the table below. What is the energy of the electron in the ground state? What is the energy of the electron in the first excited state? If the electron makes the transition shown by the red arrow, from B to C, will a...
