Protons are the positively charged particles which are present in the nucleus of a hydrogen atom. The mass of a proton is 1.6726219 × 10-27 kilograms.
Mass of proton
The mass of a proton is equal to that of the hydrogen atom. A hydrogen atom consists of one electron and one proton. As the mass of an electron is considered to be negligible therefore it can be said that the mass of a hydrogen atom is equal to the mass of a proton. The mass of a proton is 1840 times the mass of an electron.
|Mass of proton = 1.676 × 10-27 kg = 1.676 × 10-24 g = 1.6726219 × 10-27 kg|
Charge of proton
The charge of a proton is equal to and opposite to that of an electron. Thus, it has a unit positive charge.
|Charge on a proton = + 1.602 × 10-19 coulombs|
