How do elementary particles acquire charge?
That's interesting. So, can particles have fractional charges?
Yes, particles can have fractional charges. For example, quarks, which are the building blocks of protons and neutrons, have fractional charges. The standard unit of charge is the electron charge, which is equal to about 1.6 x 10^-19 Coulombs, and any other charge can be expressed as a multiple of this unit.
