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.
Electric charge: +1 e; 1.602176634×10−19 C
Charge radius: 0.8414(19) fm
Mass: 1.67262192369(51)×10−27 kg; 938.272...
Electric polarizability: 1.20(6)×10−3 fm3
