검증된 단계별 안내1
Recall the structure of an atom, which consists of a nucleus and an electron cloud surrounding it.
Understand that the nucleus contains protons and neutrons, which are collectively called nucleons.
Recognize that electrons are subatomic particles that orbit the nucleus in the electron cloud, not inside the nucleus.
Identify that among the options given (Neutron, Electron, Proton), the electron is the particle not found in the nucleus.
Conclude that the correct answer is Electron because it is located outside the nucleus, unlike protons and neutrons.
