Guida verificata passo dopo passo1
Recall the three main subatomic particles: protons, neutrons, and electrons.
Understand that protons have a positive charge and are located inside the nucleus.
Know that neutrons have no charge (are neutral) and are also located inside the nucleus.
Recognize that electrons have a negative charge and are found outside the nucleus in electron clouds or orbitals.
Therefore, the subatomic particle with a negative charge found outside the nucleus is the electron.
