1
New cards
Pauli exclusion principle
________: only 2 electrons can occupy an orbital and their spins must be paired.
2
New cards
Hunds rule
________: when orbitals of equal energy (called degenerate) are available but there arent enough electrons to fill all of them completely, one electron is added to each orbital before a second one is added to any of them; spins of the single electrons in the degenerate orbitals should be aligned.
3
New cards
wavelike nature
The ________ of an electron that prefers to be delocalized, spreading the electron density over a large volume space.
4
New cards
Electrons
________ are drawn as arrows.
5
New cards
Aufbau principle
________: orbitals fill in order of increasing energy, from lowest to highest.
6
New cards
Orbital
________: a region of space that can hold 2 electrons and has a specific quantized energy.
7
New cards
Orthogonal
________: orbitals have no net overlap.
8
New cards
Ionization potential
________: the energy it takes to remove an electron from an atom or molecule.
9
New cards
Energy
________: the ability to do work.
10
New cards
Shells
________ are divided into subshells (spdf)
11
New cards
Quantization
________: only specific values of energy are possible.
12

Energy level diagrams
________: pictorially designate where electrons are placed in an electron configuration.

________ in lower energy orbitals are held tightly to the nucleus.
