In an atom, which particle is located outside the nucleus?

Explanation:
In atoms, the nucleus is a tiny, dense core made up of protons and neutrons, while electrons occupy regions around it called the electron cloud or orbitals. Electrons are held in place by the attraction between their negative charge and the positive charge of the protons in the nucleus, so they exist outside the nucleus rather than inside it. Quarks reside inside protons and neutrons, so they’re inside the nucleus. Protons and neutrons themselves are the particles that make up the nucleus. So the particle located outside the nucleus is the electron.
