A proton has a much greater mass than an electron. Specifically, a proton is approximately 1,836 times heavier than an electron.
Mass Comparison
- The mass of a proton is about 1.6726×10−271.6726\times 10^{-27}1.6726×10−27 kilograms.
- The mass of an electron is about 9.109×10−319.109\times 10^{-31}9.109×10−31 kilograms.
- This means the proton's mass is roughly 1,836 times greater than that of the electron.
Charges of Proton and Electron
- Although their masses differ greatly, the magnitude of the electric charge carried by a proton (positive) and an electron (negative) is exactly the same, just opposite in sign.
Thus, in terms of mass, the proton is significantly greater than the electron.
