How to use in-sentence of “have a charge”:
+ Up, charm and top quarks have a charge of +.
+ Since antimatter has the opposite of charge of regular matter, anti-tauons have a charge of +1, and can be written as τ.
+ The three kinds of neutrino have a charge of 0.
+ One down quark has a charge of -1/3, and two up quarks have a charge of +2/3 each.
+ Up quarks have a charge of +, so π has charge of +1.
+ Since up quarks have a charge of +2/3, and each down quark has a charge of -1/3 this results as giving 2/3 -1/3 -1/3 = 0 charge.
+ Tau have a charge of -1, and can be written as τ.
+ Antiparticles have charge opposite to their particles, so up antiquarks have a charge of −.
