- Hyphen Notation: Name-Mass
- Isotope Notation: Mass # Symbol
- Atomic #
- APE MAN: Atomic Number = Protons = Electrons
- Mass Number - Atomic Number = Neutrons
- Democritus: Discovered all matter made of small particles called atoms
- Wrong about atoms being indivisible
- Dalton: Atomic Theory (4 Postulates)
- Wrong about 1st postulate: Matter is divisible (Rutherford-Proton, Thomson-Electron, Chadwick-Neutron)
- Wrong about 2nd postulate: Not all atoms of the same element are identical (Soddy-Isotopes)
- Thomson: Cathode Ray Tube Experiment
- Came up with plum pudding model (Electrons embedded into + charged sphere of uniform density (wrong))
- Discovered electron
- Rutherford: Gold Foil Experiment
- Discovered nucleus and protons
- Nucleus is very dense and has + charge
- The atom is mostly empty space
- Bohr: Bohr Model (planetary model)
- Electrons existed in specific orbits of fixed energy
- Coulomb's Law: Energy of attraction/replusion increases as the magnitudes of the charges increases (how many portons)
- Energy of attraction/repulsion decreases as the distance between the charges increases.
- Opposite charges attract
- Same charges repulse
- Average Atomic Mass (AAM): AAM = Mass1 (% Abundance / 100) + Mass2 (% Abundance / 100) + ...
- Mole Conversion:
- Grams to Moles: X Grams (1 mol / Atomic Mass in Grams) = Y Mol of Whatever Element
- Moles to Grams: X mol (Atomic Mass in Grams / 1 mol) = Y Grams of Whatever Element
- Moles to Atoms: X mol (6.022x10^23 atoms / 1 mol) = Y Atoms of Whatever Element
- Grams to Atoms: X Grams (1 mol / Atomic Mass in Grams)(6.033x10^23 / 1 mol) Don't Round
