WebAmong the three constituents of an atom, electrons have the lowest mass. The mass of one electron is around 1,800 times less than a proton. If calculated, it comes to 9.10938356 × 10-31 kilograms. Electron … WebAnyway, the answer to your question is: Mass of proton : 1,6726 x 10 (-27) kg. Mass of neutron: 1,6749 x 10 (-27) kg. Mass of electron: 0,00091x10 (-27) kg. The mass of each particle is very small, as you might notice from the numbers. As you see from this information, the mass of a neutron is greater than the mass of a proton because the ...

Electron mass - Wikipedia

In physics, the proton-to-electron mass ratio, μ or β, is the rest mass of the proton (a baryon found in atoms) divided by that of the electron (a lepton found in atoms), a dimensionless quantity, namely: μ = mp/me = 1836.15267343(11). The number in parentheses is the measurement uncertainty on the last two digits, corresponding to a relative standard uncertainty of 6.0×10 . Webm = proton mass. The proton's specific charge is equal to e/m. e = 1. 6 × 10 - 19 C and m = 1. 67 × 10 - 27 K g. Thus specific charge mass ratio of proton = 9. 67 × 10 7 C K g - 1. … nbc news midterm
