Question

what is the discover of proton​

Answer 1

Answer:

proton is a subatomic particle, symbol p or p⁺ , with a positive electric charge of +1e elementary charge and a mass slightly less than that of a neutron. Protons and neutrons, each with masses of approximately one atomic mass unit, are collectively referred to as "nucleons".,.Charge radius: 0.8414(19) fm

Electric charge: +1 e; 1.602176634×10−19 C

Composition: 2 up quarks (u), 1 down quark (d)

Mass: 1.67262192369(51)×10−27 kg; 938.27208816(29) MeV/c2; 1.007276466621(53) u

Symbol: p, p+, N+, 1; 1H+

Electric dipole moment: < 5.4×10−24 e⋅cm

Electric polarizability: 1.20(6)×10−3 fm3

Answer 2

Answer:

• The quark content of a proton. The color assignment of individual quarks is arbitrary, but all three colors must be present. Forces between quarks are mediated by gluons.
