Step 1
The up quark has a charge of +2/3 and the down quark has a charge of -1/3. Therefore, the combination of quarks for a proton is uud (up, up, down). Show more…

Protons and neutrons are made from combinations of the two most common quarks, the $u$ quark (charge $+\frac{2}{3} e$ ) and the $d$ quark (charge $-\frac{1}{3} e$ ). How could three of these quarks combine to make (a) a proton and (b) a neutron?
List all the possible quark triplets formed from any combination of up, down, and charmed quarks, along with the charge of each.
