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...
Together, protons and electrons form an atom'snucleus. A proton has a positive charge that counters the electron's negative charge. When an atom has the same number of protons and electrons, it is in a neutral state. Electrons are unique from the other particles in multiple ways. They exis...
