Which of the following values represents the mass of an electron?

The mass of an electron is approximately 9.1093826 x 10^(-31) kg. This value is specifically defined in physics and is fundamental to our understanding of atomic and particle physics. Electrons are one of the primary components of atoms, and their mass is significantly lighter than that of protons and neutrons, which helps explain the atom's overall structure and behavior.

In contrast, other options offer values that represent different physical constants or masses. For example, one option reflects the mass of a proton, while another represents the mass of the Sun. The last option lists a value closely related to Planck’s constant, which is used in quantum mechanics and provides the scale of quantum effects, but it is not related to mass. Each of these alternatives is therefore incorrect for representing the mass of an electron.
