Feb 12, 2019 · The third column shows the masses of the three subatomic particles in "atomic mass units." An atomic mass unit (\(\text{amu}\)) is defined as one-twelfth of the mass of a carbon-12 atom. Atomic mass units (\(\text{amu}\)) are useful, because, as you can see, the mass of a proton and the mass of a neutron are almost exactly \(1\) in this unit ...

Properties of Protons. The positive charge of protons makes the nucleus also positive. We consider an atom as neutral because it has the same number of protons and electrons. The absolute mass of a proton is 1.6726 x 10-27 kg. Its absolute charge is 1.6022 x 10-19 coulomb of a positive charge.

An electron is a tiny particle with a mass of 9.108 × 10 − 28 g and a negative charge. All neutral atoms contain electrons. The mass of a proton is 1.6726 × 10 − 24 g, or about 1836 times the mass of an electron. The proton carries a positive electrical charge, that is equal in magnitude to the charge of the electron but opposite in sign.
Mass of Proton: The mass of a proton is 1. 6726 × 10-24 g or about 1836 times the mass of an electron. The proton carries a positive electrical charge. Mass of Neutron: The mass of a neutron is 1. 675 × 10-24 g. A neutron is a particle with no charge. The ratio between the masses of electron, proton, and neutron is 1: 1837: 1838
