A neutron.
There are two up quarks and one down quark in a proton.
Ans 1 Any with a combination of an up, charm, or top quark, and a combination of two down, strange, or bottom quarks. ([(+2)+(-1)+(-1)=(0)]). Ans 2 Two down quarks and an up quark. This combination is a neutron. A down quark has a charge of -1/3 and an up quark a charge of +2/3
Protons contain two up quarks and one down quark, while a neutron contains two down quarks and one up quark.
You get a neutron! down+down+up = neutron up+up+down= 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.
They are subatomic particles. A neutron is composed of two down quarks and one up quark, and the proton of two up quarks and one down quark
Protons and neutrons are made of smaller particles called quarks. Protons are composed of two up quarks and one down quark, while neutrons are composed of two down quarks and one up quark. These quarks are held together by the strong nuclear force.
A proton is made up of two up quarks and one down quark.
A proton is made of two up quarks and one down quark, which are elementary particles that are held together by the strong nuclear force.
There are no quarks in an electron. Electrons are leptons, which are not made of quarks. Further, the electron is a fundamental particle, just like the quark. That means that neither quarks or electrons are made up of other particles, per the Standard Model of particle physics.
Yes, contrast to Proton which is made up of Two up and one down quark.
Yes, a proton is built from two up-quarks and one down-quark.
