37
Atomic Theory Timeline: | The Greeks
- An atom cannot be cut into smaller pieces - Everything is made up of atoms - Identical
38
Atomic Theory Timeline: | Dalton
- All elements are composed of atoms - Atoms of same element are exactly alike - Atoms cannot be created or destroyed
39
Atomic Theory Timeline: | Plum Pudding/Muffin model
THOMSON | -Protons, neutrons, electrons randomly scattered , no nucleus
40
Atomic Theory Timeline: | Gold foil

41
Atomic Theory Timeline: | Planetary
BOHR | -Fixed energy levels for electrons
42
Atomic Theory Timeline: | Modern atomic model
CHADWICK - Nucleus that has protons and neutrons - The nucleus is surrounded by a cloud of electrons
43
How is the periodic table organized?
- Increasing atomic number - Families and groups based on characteristics - Generally, atomic mass is increasing from left to right
44
