Our Take

Charge is an elementary characteristic of matter, all particles have a charge, even if that charge is zero (we’re looking at you, neutrons). We can quantify charge and then we know how it will react in association with other charges - whether they will be attracted or repelled and with how much force.

Book Definition

An electrical property of the atomic particles of which matter consists, measured in coulombs.
