2. How did Rutherford discover his improved version of an atomic model?

  • They used a large amount of heat and managed to split apart the atom, which they studied underneath a microscope
  • alpha particles fired straight at a thin sheet of gold. They expected most of them to be deflected by the possitive pudding, but most passed straight through, with some being deflected back
  • They used an electron microscope
  • They found faults in the plum pudding model, so they guessed what it should be

3. Jonh Dalton described atoms as...

  • Clear solid spheres with pigment in the nucleus
  • Solid spheres, with different elements made up of different spheres
  • Small circular blobs with tiny whizzing particles within them
  • A positively charged pudding, with randomly dotted electrons throughout

  • True
  • False

5. What was added to Bohrs model to explain why som elements are inert?

  • different types of nucleus
