|---|---|---|---|---|---|
| orbital | a region of space around the nucleus where the probability of finding an electron is high
🗑

||||
| Noble Gas shortcut notation | a way of showing electron configuration that starts with the previous noble gas and continues until the desired atom is reached
🗑
|
||||
| Aufbau | the rule that states that you must fill orbitals of lower energy before filling orbitals of higher energy
🗑
|
||||
| Hund's rule | orbitals of equal energy are filled separately, then double up as needed
🗑
|
||||
| Pauli exclusion principle | no two electrons can have the same "address" so we use one up arrow and one down arrow for electrons in the same orbital
🗑
|
||||
| orbital notation | a way of showing the location of electrons by using arrows in boxes or on lines
🗑
|
||||
| electron configuration | a way of showing the arrangement of electrons in an atom such as 1s2 2s2 2p5 for fluorine
🗑
|
||||
| valence electrons | electrons in the highest (outermost) energy level (shell) that can be involved in forming chemical bonds
🗑
|
||||
| s orbital | a spherical shaped orbital that can hold two electrons
🗑
|
||||
| p orbital | a bowtie shaped orbital: three of these can hold two electrons each (total of 6 electrons)
🗑
