what is the plum pudding model
the idea the an atom was a positive sphere and had electrons scattered around it
1 of 5
what is the gold foil experiment?
an experiment where alpha particles were shot at a gold foil
2 of 5
what did the gold foil experiment prove?
That there was mass centered in the middle and that the nucleus was small
3 of 5
what happened to the alpha particles fired at the gold foil?
99% of the particles went through and the rest were deflected at an angle
4 of 5
what are the differences between the plum pudding model and the new atom model?
the plum pudding model has electrons scattered around it where as the new model has electrons on the outer shells. Secondly the new model has a nucleus with protons and electrons whereas the plum pudding model is just one big sphere proton.
