- 1What did scientists conclude about the charge on the 'pudding part' of an atom? [1](an equal amount of) positive charge
- 2What caused the plum pudding model to be replaced? [2]alpha particles deflected
backwards [1]
measurements / results could
not be explained by ‘plum
pudding’ model [1] - 3Suggest one reason why other scientists thought this experiment provided valid evidence for a new model of the atom?many/(over)100 000
measurements/results taken - 4Why is there a repulsion force between the nuclei of atoms?nuclei have the same charge
- 5Why is fusion better than fission? [2]releases more energy (per kg) [1]
produces little/no radioactive
waste [1] - 6Suggest one important consequence of developing nuclear fusion power stations to generate electricity.makes another source of
energy available
increases supply of
electricity
able to meet global
demand
less environmental
