Quarks and electrons are the smallest things we know of and are called fundamental particles. Together, quarks and electrons combine to make atoms—the quarks combine to form the protons and neutrons. Quarks and electrons both have an electric charge, but electrons are always negative and quarks can be either positive or negative depending on what flavor (type) you have. Quarks also have a property called color which refers to the strong force that attracts quarks together. Quarks are always found with other quarks (such as inside a proton), but electrons can be on their own.
