SUMMARY
The mass of an electron (e-) is established as 0.000 548 u, derived from its charge and mass-to-charge ratio. The charge of the electron was initially measured using the Oil Drop Experiment, a pivotal method in experimental physics. This calculation does not involve binding energy considerations, focusing solely on the fundamental properties of the electron. The textbook example references Helium-4 with a mass of 4.002 603 u, providing context for the electron's mass in atomic physics.
