The mass of a proton is approximately 1.67 x 10^-27 kilograms, which is roughly 938 times the mass of an electron. The charge of a proton is positive and equal in magnitude to the charge of an electron, which is around 1.6 x 10^-19 coulombs.
Yes, the neutron has a negative charge and a mass that is smaller than the mass of a proton.
The particle that fits this description is a proton. Protons have a mass of approximately one atomic mass unit and a unit positive charge.
The mass of an electron is much smaller than the mass of a proton. An electron has a charge of -1, while a proton has a charge of +1.
If you compare the mass of a positron to an electron, or of a proton to an anti-proton, and so forth, the mass is the same, even though the charge is reversed. Negative charge does not mean negative mass, it has no bearing on the mass.
A proton has a positive electrical charge and is approximately 2000 times the mass of an electron.
