In the Bohr model, how do electrons travel?

• Electrons move in and out of the nucleus

• Electrons do not move

• Electrons move in circular orbits around the nucleus

• Electrons move in a straight line

True or false: electrons can change their orbit by emitting or absorbing energy

• True

• False

True or False: electrons have more energy the farther they are from the nucleus

• True

• False

In the bohr model,do the orbits of an atom have a set size and energy?

• no

• yes

How is an atom in the bohr model charged?

• Negatively charged nucleus and electrons

• Positively charged nucleus and electrons

• Negitive electrons positive nucleus

• Positive electrons negitive nucleus

What is N defined as in the bohr model?

• a letter

• Principal quantum number

• Principal quantum variable

• a quantitiy

Which atom was bohr's model compatible with?

• Hydrogen

• oxygen

• iron

• cobalt

true or false: bohr was the first to theorize that electrons existed

• TRUE

• FALSE
