Verified step by step guidance1
Recall the basic structure of an atom, which consists of a nucleus and electrons surrounding it.
Understand that the nucleus contains protons and neutrons, which are tightly bound together and do not orbit.
Recognize that electrons are the subatomic particles that move around or orbit the nucleus in defined energy levels or shells.
Identify that alpha particles are not subatomic particles but rather consist of two protons and two neutrons bound together, typically emitted during radioactive decay.
Conclude that the subatomic particle that orbits the nucleus of an atom is the electron.
