Unit 4 Electron Arrangement Test

characteristic properties of all waves frequency, wavelenght, speed, amplitude
at what speed to all electromagnetic waves travel in a vacuum 3x10^8 m/s
continuous spectrum of white light refracted into all colors
atomic emission spectrum each element has a certain spectrum- certain wavelengths+frequencies- each element has its own unique line spectrum
2 ways behavior of electrons can be described waves and particles
waves formula c= v times wavelength
particles formula E=hv
Heisenberg's Uncertainty Principle you cannot determine the position and momentum of an electron at the same time
4 quantum numbers principle qn, angular qn, magnetic qn, spin qn
3 rules for writing electron configurations Aufbau Principle, Poli exclusion principle, hund's rule
aufbau principle electrons enter 1 at a time to the lowest energy orbitals until all electrons have been accounted for
pauli exclusion principle an orbital can hold at most 2 electrons; 2 electrons must have different spins
hund's rule electrons occupy equal energy orbitals so that a max # of unpaired electrons result- dont pair up until they have to

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.
