I don't know much about quarks but if a proton is uud and a neutron is udd, is the (mass of a neutron)-(mass of proton)=mass of a down quark?
Protons and neutrons are both subatomic particles found in the nucleus of an atom. The main difference between them is their charge - protons have a positive charge and neutrons have no charge. Additionally, protons are slightly more massive than neutrons.
The composition of a particle is determined by the types of quarks that make up its structure. A proton is composed of two "up" quarks and one "down" quark (uud), while a neutron is composed of one "up" quark and two "down" quarks (udd).
Protons and neutrons interact through the strong nuclear force, which is responsible for holding the nucleus of an atom together. This force is mediated by the exchange of particles called gluons.
In certain nuclear reactions, a proton can be converted into a neutron or vice versa. This process is known as beta decay and involves the conversion of an "up" quark into a "down" quark (or vice versa) and the emission of an electron or positron.
The arrangement of quarks in a proton and neutron is significant because it allows for the stability of these particles. The combination of two "up" quarks and one "down" quark in a proton creates a net positive charge, while the combination of one "up" quark and two "down" quarks in a neutron creates a net neutral charge. This balance of charges contributes to the overall stability of the atom.
