How many generations do leptons and quarks have in the Standard Model?...

In the Standard Model of particle physics, both leptons and quarks come in three generations. Here's a detailed explanation:
Leptons

Leptons are elementary particles that do not undergo strong interactions. They are either charged (electron-like) or neutral (neutrino-like).
The three generations, or flavours, of leptons are the electron and electron neutrino, the muon and muon neutrino, and the tau and tau neutrino.
Each generation is progressively heavier than the previous one, with the electron being the lightest and the tau being the heaviest.

Quarks

Quarks are elementary particles that undergo strong interactions. They are always found in combinations to form composite particles known as hadrons.
The three generations of quarks are the up and down, the charm and strange, and the top and bottom.
As with leptons, each quark generation is heavier than the previous one, with the up and down quarks being the lightest and the top and bottom quarks being the heaviest.

Generations in the Standard Model

The existence of these three generations is a fundamental aspect of the Standard Model.
Each generation consists of two quarks and two leptons, for a total of four particles.
While it is theoretically possible for more generations to exist, experiments have so far only confirmed the existence of these three.
