Subatomic and Isotopes Review
2
3
John Dalton
Billiard Ball Model
All matter is made of atoms
Atoms of an element are exactly the same
Atoms are indestructible & uncuttable
4
JJ Thomson
Plum Pudding Model / Chocolate Chip Cookie Model
Atom is made of smaller particles
Discovered the electron
Electrons are scattered throughout
5
Ernest Rutherford
Nuclear Model
Gold Foil experiment
Nucleus is a small, dense, positively charged center
Atom is mostly open space
Electrons scattered outside the nucleus
6
Niels Bohr
Planetary Model
Mass of atom is mostly in the nucleus
Electrons move in orbits around the nucleus
7
Erwin Schrodinger
Electron Cloud Model
Electrons DO NOT orbit the nucleus
Electrons whirl around nucleus at high speeds

Calculating Average Atomic Mass
Step 1) Multiply the mass and the abundance for each isotope.
Step 2) Add them together to find the total Mass Abundance.
Step 3) Divide the total by 100.
