How many protons does an alpha particle have? What quarks make up a proton? Who discovered electrons? What is an example of a subatomic particle? What is the atomic mass of an alpha particle? What do quarks have to do with radioactive decay? What is the most im...
What is the symbol for the isotope with 80 protons and a mass number of 202? How many neutrons does it have?Mass Number:The mass number of an atom represents the number of nucleons in the nucleus of an atom. Nucleons is a general term for par...
We have calculated the proton charge radius by assuming that the real proton radius is not unique and the radii are randomly distributed in a certain range. This is performed by averaging the elastic electron-proton differential cross section over the form factor cutoff. By using a dipole form ...
The second, GJ 1214b, is smaller, with a radius roughly 2.7 times that of Earth. Both exoplanets orbit very close to their host stars and are therefore quite warm by Earth standards. Owing to intensive observational scrutiny since their respective discoveries, these two planets have become the...

Protons can also contain a charm quark, an elementary particle that's 1.5 times the mass of the proton itself. Even weirder, when the proton does contain the charm quark, the heavy particle still only carries about half the proton's mass. You may like Einstein wins again! Quarks obey...
