Guida verificata passo dopo passo1
Recall that an atom is composed of three main subatomic particles: 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.
Note that the nucleus of an atom contains protons and neutrons, but not electrons.
Since the question asks for the subatomic particle with a negative charge, focus on the particle outside the nucleus with a negative charge.
Identify the electron as the subatomic particle that carries a negative charge.
