- Model of the atom has changed over time as new evidence has become avaliable
- Evolution of Atomic Structure Over Time
- Thompson: plum pudding model- negatively charged e- move in sea of deloca. ele
- Rutherford: mass conc. in + nucleus, e- orbiting it- neutral
- Bohr: suggested that e- orbiting at specific distances; planetary model
- p + n + e-, p + n found in nucleus; smaller quarks, e- surround central nucleus

- Dalton: ele. composed of indivisible atoms
- Atoms: tiny and indivisible
