Guida verificata passo dopo passo1
Recall the structure of an atom, which consists of a nucleus and the space surrounding it called the electron cloud or orbitals.
Identify the particles found in the nucleus: protons (positively charged) and neutrons (neutral).
Understand that electrons are negatively charged subatomic particles that move around the nucleus in the electron cloud.
Recognize that positrons are not typically found in atoms; they are the antimatter counterparts of electrons.
Conclude that the subatomic particle located in the space surrounding the nucleus is the electron.
