The up quark charge 23e and down quark charge 13e make up protons and neutrons and are thus the ones observed in ordinary matter. Since it had never been written down there was no spelling for the term that he pronounced as quork The spelling of quark an elementary particle of matter smaller than a proton or neutron comes from Joyces Finnegans Wake.
A quark is one of two currently recognized groups of fundamental particles which are subatomic indivisible at least as far as we know today particles that represent the smallest known units of matter. They are the lightest and most stable. Quark definition is - any of several elementary particles that are postulated to come in pairs as in the up and down varieties of similar mass with one member having a charge of 23 and the other a charge of 13 and are held to make up hadrons.
