A little bit behind material wise, but I'm sure it'll be stuck in your heads for a while. ;)

we should all remember that ap biology is and always will be better than this class. NEWSWANGER FTW

Everybody psyched for the big test?! :D
Don't forget, stuff to know!!!
1. Lewis symbols and the octet rule
2. covalent and ionic bonding!!
3. bond polarity/electronegativity! IONIC LATTICES
4. know how to draw lewis structures! AND RESONANCE STRUCTURES
5. know the exceptions to the octet rule (odd #, more than octet, less than octet)
6. bond enthalpies and the subsequent strengths of covalent bonds!

Really good for those who want to brush up on their elemental facts ;)

Award winning periodic table, with user-friendly element data and facts. Cool, online chemistry videos, dictionary, tools and forum.

we at ap chemistry hope everyone is enjoying vacation! with extra time on your hands, why don't you brush up on some atomic radii?!

12/20/2011

everybody study their formulas for tomorrows big exam!!!
1. de broglie matter wavelength equation
2. energy of a photon equation
3. change in energy level and energy level of an electron (in joules and kJ) **
4. quantum numbers!!!
5. orbitals! and their orientation in space!
6. Hund's, Aufbau's, and Pauli exclusion principle!!!

***remember, the energy will be negative. the less negative the energy, the higher the energy.

GOOD LUCK EVERYONE!!!

Okay, okay..it seems people have trouble with determining quantum numbers, so lets go over the rules.
n: principal quantum number. any number from 1-7
l: azimuthal quantum number. any number from 0 to n-1.
m sub l. (ml) : magnetic quantum number. any integer from negative l to l. including zero.
m sub s. (ms) : spin. either positive or negative 1/2.

for 2p^6, the n would be 2, l would be 1, ml would correspond to the number orbital (-1,0,1) and ms would be +/- .5

AP BIO was better >:0
