Bonding:
Formal Charge: # Valence Elec. - (nonbonding Elec + 1/2 Bonding Elec.)
Gases: 
STP = Standard Temperature and Pressure ( 273 K or 0 C and 1 Atm)
Ideal Gas Law:
R=0.0821 Atm x L/Mole x K
Pressure (P): Always in Atm
760 mmHg = 1 Atm
760 Torr = 1 Atm
101,326 Pascal = 1 Atm
Temperature(T): Always in Kelvin =
# of Moles (n)
Volume (V): Always in Liters

Boyles law: Occurs when T and N are constant

.All material objects are composed of atoms. An atom consists of a nucleus and a vast region of space outside the nucleus. Electrons are present in the region of space outside the nuclues. Electrons are often removed from and a dded to an atom by normal everyday occurrences. The nucleus contains positively-chargedd protons and nuetral neutrons. these prtons and nuentrons are not removable or disturbable by usual everyday methods. one sure truth of this unit is that the porotn and neutron will remain within the nucleus of the atom.
Methods of charging:-friction:Having an excess of electrons thr rubber ballon is charged negatively.The shortage of electrons on the animal fur leaves it with a positive charge.-Induction: is a very common method of charging an object. IS a method used to charge an object without actually touching the object to any other charged object.- ... (Continuous)
