In the gold foil experiment, a thin sheet of gold was bombarded with alpha particles. Almost all the alpha particles passed straight through the foil. Only a few alpha particles were deflected from their original paths. 59 State one conclusion about atomic structure based on the observation that almost all alpha particles passed straight through the foil. [1] Highlight box for Answer | Atoms are mostly empty space. |
60 Explain, in terms of charged particles, why some of the alpha particles were deflected. [1] Highlight box for Answer Alpha particles are positive and are repelled by the nucleus that is also positive. Both protons and alpha particles are positively charged so they repel each other. Protons and alpha particles have the same charge. |
