Right now, trillions of particles from the Sun are streaming through your body every second. You feel nothing, and they leave no mark.
The particle doing it carries no electric charge. It also has almost no mass.
Compare the neutrino with the electron, the lepton you already know.
Later in this topic you will see why the neutrino passes through you — and through the whole Earth — almost without interacting.
What electric charge does the neutrino carry?
Nora says the neutrino's mass is almost nothing. Is Nora correct?
Which two properties describe the neutrino?
Billions of particles from a nuclear power station pass through its thick walls as if nothing were there. Which particle fits?
Trillions of one kind of lepton stream through your body every second, almost never interacting. Type its name.
