quantum numbers

TermDefinition
quantum numbers specify the properties of atomic orbitals and the properties of electrons in orbitals
quantum numbers Principal, Angular Momentum, Magnetic, Spin
principle quantum number symbolized by n, indicates the main energy level occupied by the electron
subshell quantum number the quantum number that indicates the shape or type of orbital
ground state The lowest energy state of an atom
not excited and as close to the nucleus as possible
n = 1 there is only one sub
n =2 there are two possible subshell shapes (s,p)
n = 3 there are three subshells possible (s,p,d)
n = 4 there are four subshells possible (s,p,d,f)
n = 5 there are five subshells possible (s,p,d,f,g)
shapes different subshells have different ________
shape the subshell number can also tell us of the atom's _____
spherical the s orbital may be pictured as having a _____shape
dumbell shape p orbital may be pictured as having a
magnetic the third quantum number that is symbolized by the letter m...indicates the orientation of an orbital around the nucleus
(x ,y
spin The quantum 4th number that has only two possible values, +1/2 and
opposite two electrons in any given energy level must have _______ spins
same two electrons in the same orbit cannot have the _____ spin number
Pauli exclusion principle The principle that states than An atomic orbital may at most two electrons, each with opposite spin direction
electrons there are the same number of protons as there are ______ when speaking of the electronic configurations
lowest Electrons occupy the ______ energy levels first before filling the next level
aufbau the principle rule stating that electrons occupy the orbitals of lowest energy first
hunds rule stating that all sub shells must have at least 1 e
p only six electrons can occupy any ___ sub shell
d only 10 electrons can occupy any ___ sub shell
f only 14 electrons can occupy any ___ sub shell
Lewis symbol which shows the valence electrons as dots arranged around the atomic symbol.

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.
