What is leptons and quarks?
A quark is an elementary particle and a fundamental constituent of matter. Quarks combine to form particles called hadrons (the most stable of which are protons and neutrons). A lepton is an elementary particle and a fundamental constituent of matter. The best known of all leptons is the electron.
What are leptons within the charged particles ecosystem?
There are three well-known leptons that are electrically charged: Electron (e), Tauon (τ), and Muon (μ).
What is lepton family?
Leptons are divided into three lepton families: the electron and its neutrino, the muon and its neutrino, and the tau and its neutrino. We use the terms “electron number,” “muon number,” and “tau number” to refer to the lepton family of a particle.
What are the different types of leptons?
There are 6 types of leptons: electron, electron neutrino, muon, muon neutrino, tau and tau neutrino. For each of these, the neutrino brand carries a neutral charge, while their counterparts all have a negative charge.
How do leptons decay?
The best known of all leptons is the electron. Electrons have the least mass of all the charged leptons. The heavier muons and taus will rapidly change into electrons and neutrinos through a process of particle decay: the transformation from a higher mass state to a lower mass state.
Which of the following is an example of a lepton?

Is antineutrino a lepton?
An antineutrino is the antiparticle partner of the neutrino, meaning that the antineutrino has the same mass but opposite “charge” of the neutrino. Although neutrinos are electromagnetically neutral (they have no electric charge and no magnetic moment), they may carry another kind of charge: lepton number.
