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 |
