Episode 522: The Size of the Nucleus
Starting from Rutherford's electron scattering experiment, these activities from the Institute of Physics, encourage students to consider experimental evidence for the size of the nucleus. Students look at alpha particle scattering and distance of closest approach. The learning episode examines:
* worked example on the size of the nucleus
* atomic size
* forces and closest approach
* atomic number and the charge on a nucleus
* the upper limit of nuclear size
