• Nuclear model

  By Earnest Rutherford
• Nuclear model

  Discovered between 1909-1911
• Who discovered the protons?


  Earnest Rutherford
• proton

  2nd subatomic particle that was found
• Experiment that Earnest Rutherford did

  Alpha scatering experiment
• Alpha scattering experiment

  Positively charged alpha particles were fired at a thin sheet of gold foil.
• Alpha scattering experiment

  Found that most alpha particles pass straight through the gold foil.
• Why did they suggest that most of the storm is empty space?

  Because some alpha particles pass straight through it.
• Some alpha particles changed direction(deflected)

  As alpha particles are positively charged, they were repelled from the nucleus.meaning it contains a positive charge.
