Sab kha hai ?​

Answer 1

Answer:

A 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 jointly referred to as "nucleons".

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

Symbol: p, p+, N+, 1; 1H+

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

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

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

Classification: Baryon

Statistic: Fermion
