The fixed amount of energy that a system described by quantum mechanics, such as a molecule, atom, electron, or nucleus, can have
What is an Energy Level
100
Abbreviating long electronic configurations.
What is Shorthand Notation
100
[He] 2s2 2p2
What is Carbon(C)
100
1s2 2s2 2p6 3s1
What is Sodium(Na)
100
Boron
What is [He] 2s2 2p1
200
Region of space around the nucleus where there is a high probability of finding an electron aka atomic orbitals
What is a Sublevel
200
Electrons occupy the orbitals of the lowest energy levels first
What is the first rule to writing electron configurations;Aufbau
200
[Ar] 4s2
What is Calcium(Cl)
200
1s2 2s1

300
S-orbitals
P-orbitals
D-orbitals
F-orbitals
What are the four Sub-levels
300
Each atomic orbital can describe 2 electrons and in order to occupy the same orbital they must have different quantum numbers
What is the second rule to writing electron configurations; Pauli Exclusion Principle
300

300
1s2 2s2 2p6 3s2 4s1
What is Potassium(K)
300
Arsenic
What is [Ar] 4s2 3d10 4p3
400
the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals
What is Electron Configuration
400
when e- are assigned to equal orbitals, one e- goes in each orbital before being paired.
What is the third rule to writing an electron configuration; Hund's Rule
400
[Ar] 3d10 4s2 4p6
What is Krypton(Kr)
400
1s2 2s2 2p6 3s2 3p6 4s2 3d10
What is Zinc(Zn)
400
Tellurium
What is [Kr] 4d10 5s2 5p4
500
a number that occurs in the theoretical expression for the value of some quantized property of a subatomic particle, atom, or molecule and can only have certain integral or half-integral values.
What are Quantum Numbers
500
By going to the previous noble gas(up one row and all the way to the right) and inserting that noble gas into [] and pretending you have written the electron configuration to this point and finishing the electron configuration.
This is a way to abbreviate long electron configurations.
