Electron Config

Electron Configuration the arrangement of electrons in the energy levels, sublevels and orbitals of atoms
S orbitals spherical orbitals; first to fill for any energy level; can only hold 2 electrons
P orbitals 3 mutually perpendicular dumbbell shaped orbitals; second to fill from 2nd energy level on up; can hold max of 6 electrons
D orbitals 5 orbitals of cloverleaf shape; third to fill for any energy level; beginning in the third shell, can hold a total of 10 electrons.
F orbitals their shapes are even more complex than s, p, or d orbitals; can hold a total of 14 electrons in 7 sub-shells; in the fourth and fifth energy levels
Aufbau Principle states that each electron occupies the lowest energy orbital available
Pauli Exclusion Principle maximum of two electrons may occupy an atomic orbital, but only if they have opposite spins
Hund's Rule electrons occupy equal energy orbitals so as to maximize the number of unpaired electrons
Principle Energy Level main energy level or distance of an electron from the nucleus; (n); correspond to the rows 1-7 on the Periodic Table
Sublevels regions within the energy levels; corresponds to the block grouping s,p,d,f on the Periodic Table
spherical s sublevel
dumbbell p sublevel
clover d sublevel
double clover f sublevel
Orbital Notation Uses circles to represent atomic orbitals with a label underneath to indicate sublevel and energy level
Noble Gas located in group 18 on the Periodic Table.
Isoelectronic two atoms that have the same number of electrons
Valence Electrons Electrons located in the outermost energy level
n Principle quantum number
l Angular momentum quantum number
ml Magnetic quantum number
ms Electron spin quantum number

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.
