Web23 de out. de 2024 · Free radicals are atoms that have one electron that is not paired. Sometimes they have more than one unpaired electron. 1. Electrons need to be paired to be stable. Free radicals constantly look to bind with another atom or molecule to become stable. 2. As they're looking around, free radicals can damage human cells. In the Standard Model of particle physics, electrons belong to the group of subatomic particles called leptons, which are believed to be fundamental or elementary particles. Electrons have the lowest mass of any charged lepton (or electrically charged particle of any type) and belong to the first-generation of fundamental particles.
