Atomic Structure - Electrons, Protons, Neutrons and Atomic Models

The wavelength of a probe is roughly a measure of the size of a structure that it can probe in some detail. The quark structure of protons and neutrons appears at the minute length scale of 10–15 m or less. This structure was first probed in early 1970’𝑠 using high energy electron beams produced by a linear accelerator at Stanford, USA. Guess what might have been the order of energy of these electron beams. Rest mass energy of electron = 0.511 MeV
