science unit B
Cards in this deck (37)
- 1Scientist J.J ThomsonRays were made up of electrons
Electron were part of an Atom (people didn't believe) - 2Scientist Chadwickdiscovered the nucleus contains protons and neutrons (they both weight the same)
- 3Scientist DaltonSuggested that matter makes up elements
Elements were composed of particles call atoms - 4Scientist BohrFrist discovered how atom moved and suggested the electron shell
- 5Scientist NagaokaRefined Bohr idea of how the electron orbit and came up with the solar system idea of how the particles move.
- 6Where is the Alkali-metals located on the periodic table?Group/Family 1
- 7Where do u find the Metalloids on the periodic table ?The Diagonal line on the right side (purple)
- 8Where are the Noble Gases found on the periodic table?Group/Family 18
- 9where is the halogens found of the periodic table?Group/Family 17
- 10Where are the Alkaline-Earth located on the periodic table ?Family/Group 2
- 11Where are the Non-Metals on the periodic table ?The group on the right side (orange)
- 12Where are the metals found on the periodic table?The middle part of the table (green)
- 13Explain the Raisin Bun ModelNagaoka came up with it. The nucleus is all positive and there are neutrons embedded in it.
