Electron Energy Level

What are the possible energy levels of an electron in an atom?

• Quantized energy levels represented by the principal quantum number (n)

• Energy levels based on the speed of the electron

• Energy levels determined by the atomic weight of the atom

• Continuous energy levels with no specific values

What is the relationship between the energy levels of an electron and its distance from the nucleus?

• The energy levels of an electron increase as it moves closer to the nucleus.

• The energy levels of an electron are inversely proportional to its distance from the nucleus.

• The energy levels of an electron are directly proportional to its distance from the nucleus.

• The energy levels of an electron are not affected by its distance from the nucleus.

Define electron transition in an atom.

• The process of an electron moving from one atom to another

• The change in the charge of an electron within an atom

• The transformation of an electron into a proton

• Movement of an electron from one energy level to another

What happens to an electron when it undergoes a transition to a lower energy level?

• It absorbs a photon of light

• It releases an electron

• It creates a new energy level

• It emits a photon of light

Explain the concept of excitation of an electron in terms of energy levels.

• When an electron splits into two smaller particles.

• When an electron loses energy and moves to a lower energy level.

• When an electron absorbs energy and moves to a higher energy level.

• When an electron stays at the same energy level.

What is the significance of the emission spectrum in understanding electron transitions?

• It has no significance in understanding electron transitions

• It shows the mass of the electron during transitions

• It indicates the speed of electron transitions

• It shows the specific wavelengths of light emitted during electron transitions.

Describe the difference between absorption and emission of light by electrons during transitions.

• Absorption of light by electrons results in the electron moving to a lower energy level, while emission of light by electrons results in the electron moving to a higher energy level.

• Absorption of light by electrons results in the electron moving to a higher energy level, while emission of light by electrons results in the electron moving to a lower energy level.

• Absorption of light by electrons results in the electron moving to a higher energy level, while emission of light by electrons does not result in any change in energy level.

• Absorption of light by electrons does not result in any change in energy level, while emission of light by electrons results in the electron moving to a higher energy level.

How does the energy difference between electron energy levels determine the frequency of emitted light during a transition?

• The frequency is determined by the speed of the electron

• E=hf

• E=mc^2

• The energy difference has no effect on the frequency
