WebThe Letters, s, p, d, and f designate the shape of the orbital's and the superscript gives the number of electrons in that orbital. Atomic Radius There are a number of different ways to measure atomic radius. Two common ones are covalent radius (measures in pirometers) and Van der Waals radius. WebHe measured the mass of the particles and discovered they were 1800 times smaller than that of the element hydrogen. This led him to conclude that these particles were a smaller piece of matter than the atom itself. He further concluded that these small particles were building blocks of larger particles.
