Guida verificata passo dopo passo1
Recall the basic structure of an atom, which consists of a nucleus and particles surrounding it.
Understand that the nucleus contains protons and neutrons, which are tightly bound together.
Recognize that electrons are the subatomic particles that move around or orbit the nucleus in defined regions called electron shells or orbitals.
Note that quarks are fundamental particles that make up protons and neutrons, but they do not orbit the nucleus themselves.
Conclude that the particle which orbits the nucleus is the electron.
