|
the fixed energies an electron can have.
|
|
|
|

|
the amount of energy required to move an electron from one energy level to another energy level.
|
|
|
|
atomic orbital
|
often throught of as a region of space in which there is a high probability of finding an electron.
|
|
|
|
electron configuration
|
the way in which electrons are arranged in various orbitals around the nuclei of atoms.
|
|
|
|
Aufbau principle
|
electrons occupy the orbitals of lowest energy first.
|
|
|
|
Hunds rule
|
states electrons occupy orbitals of the same energy in the same way that makes the number of electrons with the same spin direction as large as possible.
