Atomic Theory

Before learning anything in class, what I know about Atomic Theory:

Atom - Everything is composed of atoms
Proton - Positive
Neutron - neither positive or negative
Electron - Negative
Valance Shell - needs 8 electrons to be full
Ion - Positive or Negative Atoms
Isotope - different ways an element can be expressed
Atomic Mass/Weight - how much an element weighs
Shells - In order for bonding to occur, there needs to be 8 electrons
Bonding - can occur between two elements
