Week 10 Quiz

What are the “rings” in Bohr’s model of the atom called?

• Orbitals

• Principle energy levels

• Energy levels

• All of the above

1. As you move further away from the nucleus, what happens to the energy of an electron?

• Increases

• Decreases

• Stays the same

• Becomes proportional

1. What happens to the distance of the rings as you move further and further away from the nucleus?

• Get closer together

• Move further apart

• Stays constant

• Becomes proportional

1. What does the spacing of shells as we move further from the nucleus mean for electrons as they get excited and move up and down rings further from the nucleus?

• It takes less energy to move up and down the closer you are to the nucleus

• 1. It takes less energy to move up and down the farther you are from the nucleus

• 1. It takes the same amount of energy regardless of where you’re at in the atom

• 1. None of the above

1. Ground state is

• The lowest ring in a bohr model

• 1. The nucleus

• 1. The lowest energy level an electron can be

• 1. None of the aboveWhen an electron is out of energy

1. How do electrons move to different energy levels?

• They gain more energy than they need so they hang out a while in the nearest sublevel

• 1. They gain just the right amount of energy to move to a specific sublevel

• 1. Electrons cannot move to different energy levels

• 1. Electrons cannot move upwards, they can only move downwards as they lose energy

1. What happens when electrons fall back to their ground states from their excited states?

• They do nothing

• 1. They release energy in the form of heat

• 1. They release energy in the form of light

• 1. The do both nothing, and release energy in the form of light

1. What is the relationship between energy and frequency?

• They’re directly proportional

• 1. They’re inversely proportional

• 1. They’re not related

• 1. They’re cousins

1. What is the relationship between wavelength and frequency?

• They’re directly proportional

• 1. They’re inversely proportional

• 1. They’re not related

• 1. They’re cousins
