In earlier grades you saw the electron: the tiny, negatively charged particle found outside an atom's nucleus. Physicists have probed electrons with the most powerful experiments they can build.
No experiment has ever found anything smaller inside an electron.
A new, higher-energy probe examines an electron. Based on every experiment so far, what does it find inside?
No experiment has ever found anything smaller inside an electron.
It finds nothing. As far as we can tell, the electron has no parts.
What have experiments found inside the electron?
Theo says probing an electron finds nothing smaller inside it. Is Theo correct?
Which particle has never shown any smaller parts?
Which comparison of the proton and the electron is correct?
A lab fires probes at electrons at higher and higher energies, year after year. What do all its results show?
A student says: 'Every particle must be made of smaller ones, so the electron is too.' Which statement corrects the claim?
