Quarks have fractional electric charge values – either (− 1 / 3 ) or (+ 2 / 3 ) times the elementary charge (e), depending on flavor. Up, charm, and top quarks (collectively referred to as up-type quarks) have a charge of + 2 / 3 e; down, strange, and bottom quarks (down-type quarks) have a charge of − 1 / 3 e.
Color charge is a property of quarks and gluons that is related to the particles' strong interactions in the theory of quantum chromodynamics (QCD). Like electric charge, it determines how quarks and gluons interact through the strong force; however, rather than there being only positive and negative charges, there are three "charges", commonly called red, green, and blue.
Quarks also carry fractional electric charges, but, since they are confined within hadrons whose charges are all integral, fractional charges have never been isolated. Note that quarks have electric charges of either + + 2 / 3 e or − + 1 / 3 e , whereas antiquarks have corresponding electric charges of either − + 2 / 3 ...

Several bosons, including the W and Z bosons and the Higgs boson, can decay into charm quarks. All charm quarks carry charm, a quantum number. This second-generation particle is the third-most-massive quark, with a mass of 1.27 ± 0.02 GeV/c 2 as measured in 2022, and a charge of + 2 / 3 e.
All quarks are assigned a baryon number of 1 / 3 . Up, charm and top quarks have an electric charge of + 2 / 3 , while the down, strange, and bottom quarks have an electric charge of − 1 / 3 . Antiquarks have the opposite quantum numbers. Quarks are spin- 1 / 2 particles, and thus fermions. Each quark or antiquark ...
Quarks have fractional elementary electric charge (−1/3 or 2/3) [15] and leptons have whole-numbered electric charge (0 or -1). [16] Quarks also have color charge, which is labeled arbitrarily with no correlation to actual light color as red, green and blue. [17] Because the interactions between the quarks store energy which can convert to ...
It, along with the down quark, forms the neutrons (one up quark, two down quarks) and protons (two up quarks, one down quark) of atomic nuclei. It is part of the first generation of matter, has an electric charge of + 2 / 3 e and a bare mass of 2.2 +0.5 −0.4 MeV/c 2. [1]
