Resource summary

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)
