|
Analyte
|
thing being analyzed
|
|
|
Bohr Model
|
electrons in circles around nucleus
|
|
|
Heisenber's Uncertaintly Principle
|
cannot know exactly where an electron is AND how fast it's going.
|
|
|
Para Magentism
|
parallel magnetism and all electrons going in same direction is stable. (all arrows pointing up)
|
|
|
Quantum Mechanics
|
1. main energy shell. n
2. angular momentum. l 3. orientation of l. ml ' 4. charge/spin. ms |
|
|
Aufbau principle
|
energy orbitals are assigned from lower to higher (building up)
|
|
|
Pauli Exclusion Principle
|
Two electrons occupying the same orbital have to have opposite spins (no two can have the same 4 numbers)
|
|
|
Hund's Rule
|
All orbitals must be filled before electrons can double-up in an orbital.
|
|
|
Kinetic Momentum Theory
|
1. tiny particles and distances are relativey large between.
2. gass particles move randomly, in straight lines, in all directions. 3. forces of attraction/repulsion are very small (0 but not really) except in collisions. 4. collisions are considered to be elastic (not really) 5. KE is proportional to Kelvin Temp. |

|
Ideal Gas Law
|
PV = nRT
|
|
|
Volatile
|
readily vaporizes
|
|
|
Dalton's Law of Partial Pressures
|
In a mix of gasses, the total pressure is the sum of all the individual gas pressures. Ptot = P1 + P2 + . . . . .
