| Question | Answer |
| What happens when high energy electron are fired at a thin sample of element ? | We can observe an intensity pattern A general loss of intensity with increasing angle Due to the electrons being diffracted by the positively charged nucleus |
| What can you see from the electron scattering at around 28 degrees? | A small peak from the diffraction grating effect of the atomic structure |
| What is the grating spacing in this situation the equivalent of? | The nuclear radius |
| What does nuclear radius have a relationship with? | Nucleon number (Atomic mass) |
