What is a Proton?
Protons have some different properties than the other two subatomic particles found in atoms:
-unlike electrons (which have a negative charge) and nutrons (which have a nuetral charge), protons are positively charged particles.
-there are also differences in realtive masses of the subatomic particles. Protons and nuetrons have the same mass. Electrons, however, are about 1/1840 the mass of protons or nuetrons. The difference in relative masses also shows why the nucelas (which contains only protons and nuetrons) is the most dense part of an atoma and why it is the heaviest.
A proton is a subatmic particle with a positive charge that is found in the nucleus of an atom. It is one of the three types of subatomic particles in atoms, the other two being nuetrons and elctrons
The discovery of the Proton was so impactful for a multitiude of reasons. On of the biggest is that the understanding of the Proton allowed chemists and physicists to better understand atomic theory and improve their views of the structure and nature of molecules along with the ability to enhance their information about molecular bonds.
The accepted value of a Protons charge radius (the distance upon which it can exhibit its positive charge) is only 0.8768 femtometers, however considering the size of a proton, the charge radius is substantial enough to bind two atoms together. This kind of bond (one in which two atoms are attracted because of a change in their number of electrons and a unbalanced charge) is called an Ionic bond.
