Answer:
The relative mass of an electron is 1/1836 amu.
Explanation:
Electron is one of the three main subatomic particles. It is a negatively charged particle that is denoted by the symbol e⁻. The electric charge of an electron is about −1.6 × 10⁻¹⁹ coulombs.
It is an elementary particle that has an actual mass of 9.11 × 10⁻³¹ kg which is approximately 1/1836 of the mass of the proton.
Therefore, the relative mass of an electron is 1/1836 amu.
