A proton is made up of two up quarks and one down quark.
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.
Up quarks and down quarks are in protons and neutrons.
Up quarks and down quarks are in protons and neutrons.
Protons contain two up quarks and one down quark, while a neutron contains two down quarks and one up quark.
Quarks. Up and down quarks, I think. Google quark.
Both protons and neutrons consist of "up" and "down" quarks.
Protons and neutrons are hadrons; they are made of quarks. Protons are composed of two up quarks and a down quark, while neutrons are composed of one up quark and two down quarks. The quarks are held together by gluons. Electrons are not composed of more fundamental particles; they are categorized as leptons.they are made up of quarks
3 each. A proton is composed of 2 up quarks and 1 down quark. A neutron is composed of 1 up quark and 2 down quarks.
Protons and neutrons are made from smaller substances called Quarks. A proton is made from 2 "Up quarks" and 1"Down quark" whereas a neutron is made from 2 "Down quarks" and 1 "Up quark".
The subatomic particles found in protons and neutrons are quarks. There are two types of quarks that combine to make either particle, up and down quarks. Protons are 2 ups and a down and neutrons are 2 downs and an up.
up-quarks and down-quarks
Atoms are made up of Protons and neutrons and electrons. Quarks make up Protons and Neutrons. Protons are made up of 2 up quarks and one down quark. Neutrons are made up of 2 down quarks and 1 up quark. A down quark has a charge of -1/3. An up quark has a charge of +2/3.
