Guida verificata passo dopo passo1
Recall the three main subatomic particles in an atom: protons, neutrons, and electrons.
Understand the charge of each particle: protons carry a positive charge, neutrons have no charge (neutral), and electrons carry a negative charge.
Identify the location of each particle: protons and neutrons are located in the nucleus, while electrons orbit the nucleus in electron clouds or shells.
Since the question asks for the negatively charged particle that orbits the nucleus, focus on the electron.
Conclude that the electron is the subatomic particle that carries a negative charge and orbits the nucleus of an atom.
