Question

The mass of a proton is ____ times that of an electron.

Answer 1

Mass of proton:

• Protons are positively charged sub-atomic particles present in the nucleus of the atom.
• The absolute mass of a proton is $1.672\times {10}^{-27}\mathrm{kg}$.

Mass of electron:

• Electrons are negatively charged sub-atomic particles revolving in the shells of the atom.
• The absolute mass of the electron is $9.109\times {10}^{-31}\mathrm{kg}$.

Relationship between the mass of proton and mass of electron:

• The ratio of the mass of the proton to the mass of the electron$=\frac{1.672\times {10}^{-27}\mathrm{kg}}{9.109\times {10}^{-31}\mathrm{kg}}$
• The ratio of the mass of the proton to the mass of the electron$=1835.5$$\approx 1836$

Hence, the mass of a proton is $1836$ times that of an electron.
