Electron

Subatomic particle with a negative elementary electric charge, orbiting atomic nuclei and carrying electric current.

Core Principles & Analysis

• Discovered by J. J. Thomson in 1897 through cathode ray experiments.
• Carries one negative elementary charge of 1.602 × 10⁻¹⁹ coulombs.
• Its magnetic moment is measured to about one part in 10¹³, in precise agreement with quantum electrodynamics.
