An Electron is a subatomic particle with a negative charge, usually labeled e-. Electronic is a light subcategory, is the first generation of Chinese Wikipedia does not have the first generation page, you can refer to the English Wikipedia corresponding page generation (particle physics). A member of the lepton family that interacts with other particles by gravity, electromagnetism, and the weak nuclear force. Leptons are one of the elementary particles that make up matter, meaning they cannot be broken down into smaller particles. The electron has a 1/2 spin and is a kind of fermion. Electrons and positrons collide and annihilate each other, creating more than one pair of gamma-ray photons in the process.
