Protons and neutrons have approximately the same mass. However, one proton is about 1,835 times more massive than an electron. Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well. Adding a proton to an atom makes ...
aThe charge of an electron or of a proton is much too small to be basic quantity of charge of charge for almost all practical applications. The SI unit of charge is the coulomb, with the symbol C. A coulomb of negative charge equals that of 6.242(1018 electrons. The coulomb is a deriv...
