Trends in the periodic table: Up and to the Right
|
Up and to the right: Energy of ionization, electron affinity, electronegativity
|
|
|
Trends in the periodic table: across
|
Atomic radius and metallic character
|
|
|
Char. of Metal
|
lustrous, ductile, malleable, thermally and electrically conductive
|
|
|
AMUs in one atom of Carbon 12
|
12 AMU
|
|
|
What atoms make the greatest dipoles
|
Greatest difference in electronegativity
|
|
|
Physical rxn
|
maintains molecular structure and ID. ex: melting, evaporation
|
|
|
chemical rxn:
|
changes molecular structure, creates a new compound. ex: combustion, redox
|
|
|
Emerical Formula
|
Use 100g. ex: 6g H/1g per mol
|
|
|
Prinicipal quantum #
|
Inc in # = inc in energy
|
|
|
Hund's
|
Unpaired equals parallel
|
|
|
Ideal Gas
|
PV=nRT. n=3 of moles. T= temp in K. R universal constant.
|
|
|
Ideal Gas numbers
|
1 atm. 22.4 L. 1 mole 0 degrees=273 K
|
|
|
Partial pressure
|
total pressure x mole fraction
|
|
|
Ideal gas PV/RT =1. deviations
|
vol deviation d/t vol of molecules. Pressure deviation dt intermolecular forces
|
|
|
Ideal gas characteristics
|
no vol. no forces except( other than repulsive d/t collisions). kinetic energy directionally proportional to the temp.
|
|
|
Graham's Law
|
v1/v2 = sq rt m2/ sq rt m1. notice switch. Avg speed inversely proportional to the temp.
