Definition of amu in terms of 12C?
One atom of 12C has an atomic weight of 12amu
Avagadro's number:
Value?
Definition?
6.022 x 10^23 = 1 mole

It is the number of carbon atoms in 12 grams of 12C
amu to gram relationship?
6.022 x 10^23 amu = 1 gram
Quick equation for converting grams to moles

Quick equation for converting moles to grams
moles = grams / atomic weight

grams = moles x atomic weight
Electronegativity versus electron affinity?
Electronegativity is the tendency of an atom to attract an electron in a BOND that is SHARED

Electron affinity is the willingness of an atom to accept an additional electron
10^-9?
10^-12?
10^-15?
10^-9 = nano
10^-12 = pico
10^-15 = femto
principal quantum number?
n = shell level

(think row/period number)
azimuthal quantum number?
l = n - 1 = orbital shapes

0 = S
1 = P
2 = D
3 = F
magnetic quantum number?
-l to +l

orbital orientation
ie -1, 0, +1 = Px, Py, Pz
Plank's quantum theory:
principle
equation
Electromagnetic energy is quantized in discrete units related to the wave frequency

E = hf -> h = planks constant
