Lesson 5.3 Bohr

Lesson 5.3 Bohr Atomic Model

TermDefinition
Planetary model of the atom Electrons move around the nucleus in fixed cylindrical orbits
quantized only certain values are allowed
ground state The lowest energy state of an atom
absorb to take in
emit to give off
excited state when an atom absorbs energy, its electrons move to a higher energy level
energy level diagram A schematic drawing used to arrange atomic orbitals in order of increasing energy levels.
quantum numbers numbers having only specific allowed value and used to characterize the arrangement of electrons in an atom.
electron orbital how electrons are spatially distributed surrounding the nucleus; the area where an electron is most likely to be found
energy level The shells that hold electrons
valence electrons Electrons on the outermost energy level of an atom
Bohr Model model of an atom that shows electrons in circular orbits around the nucleus

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
