| Frage | Antworten |
| Scientist J.J Thomson | Rays were made up of electrons Electron were part of an Atom (people didn't believe) |
| Scientist Chadwick | discovered the nucleus contains protons and neutrons (they both weight the same) |
| Scientist Dalton | Suggested that matter makes up elements Elements were composed of particles call atoms |
| Scientist Bohr | Frist discovered how atom moved and suggested the electron shell |
| Scientist Nagaoka | Refined Bohr idea of how the electron orbit and came up with the solar system idea of how the particles move. |

| Where do u find the Metalloids on the periodic table ? | The Diagonal line on the right side (purple) |
| Where are the Noble Gases found on the periodic table? | Group/Family 18 |
| where is the halogens found of the periodic table? | Group/Family 17 |
| Where are the Alkaline-Earth located on the periodic table ? | Family/Group 2 |
| Where are the Non-Metals on the periodic table ? | The group on the right side (orange) |
| Where are the metals found on the periodic table? | The middle part of the table (green) |
| Explain the Raisin Bun Model | Nagaoka came up with it. The nucleus is all positive and there are neutrons embedded in it. |
