The atomic mass of an electron is approximately 9.10938356 × 10-31 kilograms. This value is extremely small compared to the mass of protons and neutrons, which are the other primary constituents of an atom.
Electrons are fundamental particles that carry a negative electric charge. They are found in the electron cloud surrounding the nucleus of an atom. Despite their small mass, electrons play a crucial role in chemical reactions and the formation of chemical bonds.
It’s important to note that the atomic mass of an electron is often considered negligible when calculating the atomic mass of an atom. This is because the mass of an electron is about 1/1836 times the mass of a proton or neutron. Therefore, the atomic mass of an atom is primarily determined by the number of protons and neutrons in its nucleus.
