AS level Chemistry - atomic structure - atomic models quiz

?
Jonh Dalton described atoms as...
Solid spheres, with different elements made up of different spheres
1 of 9
J J Thompson came up with the plum pudding model, but what was it?
A spherical shape, with a positively charged pudding and randomly dotted negative electrons
2 of 9
How did Rutherford discover his improved version of an atomic model?
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

Who made modifications to Rutherfords model?
Bohr

What else did he say about the level of energy in each shell?
It is fixed
5 of 9
When an electron _ _ _ _ _ between shells, electromagnetic radiation is _ _ _ _ _ _ _ or _ _ _ _ _ _ _
moves, emmited, absorbed

What was added to Bohrs model to explain why som elements are inert?
Subshells
7 of 9
What is another atomic model that hasn't been metioned yet?

8 of 9
Why do scientists not always use the quantum model?
Becuase it can be too complex, so they use the refined Bohr model
