Answer
The mass of an electron is approximately 9.10938356 × 10^-31 kilograms. This value is extremely small compared to the mass of most objects we encounter in our daily lives, making electrons much lighter than protons and neutrons, which are the particles found in the nucleus of an atom. The mass of an electron is often used as a reference for atomic and subatomic mass measurements.
