Fundamental unit of charge
1.6*10^{19} C

Proton
1 AMU, Determines atomic number of element. +1 Charge


Electron
No Mass, 1 Charge

Avogado's Number
6.022x10^{23}; used to determine atomic weight.

Planck's Constant
6.626x10^{34}; used to determine energy value

E=hf
 E= Energy Value of Quantum
 h= Planck's Constant
 f= frequency of radiation

Rydberg Constant
2.18x10^{18} J/electron

E=(R_{H}/n^{2})
 E = Energy of an electron
 R_{H} = Rydberg Constant
 N = Principle quantum number
(Higher Quantum Number Has Higher Energy)

E=(hc/Wav)
 E= Electromagnetic Energy
 h = Planck's Constant
 c = speedd of light
 Wav = wavelength

Speed of Light In Vacuum
C = 3.00 x 10^{8}m/s

Atomic Absorbtion Spectra
Delta E is the same for any change between absorbing (moving out orbitals) and emitting (Moving in orbitals)

Heisenberg uncertainty principle
It is impossible to simultaneously determine, with perfect accuracy, both position and momentum of an electron.

N
 Principle Quantum Number
 Determines which shell the electron is in.
 Contains 2n^{2}electrons

l
 Azimutal (Angular momentum) quantum Number
 l equals all values from 0 to n1
 Electrons in Subshell = 4l+2

m_{l}
 Magnetic Quantum Number
 All intergers between l and +l
 There will always be 2l+1 possible values of m_{l}

m_{s}
 Spin Quantum Number
 Only Values of +1/2 and  1/2

n+l Rule
 Used to rank subshells in order of filling
 If a tie occurs the lower n is filled first

Hund's rule
Orbitals are filled so there are a maximum number of halffilled orbitals.

Paramagnetic vs. Diamagnetic
Paramagnetic materials are attracted by magnetic fields due to the fact that they have unpaired electrons. Diamagnetic are the opposite.

Valence Electrons
The electrons in the outer shell that are available for interaction.
