Protons and neutrons are composed of quarks. A proton is made up of two up quarks and one down quark (uud), while a neutron is composed of one up quark and two down quarks (udd).
Two up quarks and one down quark make up a proton.
Protons and neutrons are composite particles make up of up and down quarks. There are two up quarks and one down quark in a proton, and two down quarks and an up quark in a neutron.
To make a proton, which has a charge of +1, you would need two up quarks (each with a charge of +2/3) and one down quark (with a charge of -1/3) since the total charge of a proton is the sum of the charges of its constituent quarks.
A proton consists of two up quarks and one down quark bound together by the strong nuclear force. These quarks are elementary particles that are the building blocks of protons and other hadrons.
