Negatively charged particles that orbit the nucleus?

Negatively charged particles that orbit the nucleus?

• A. Electrons
• B. Protons
• C. Neutrons
• D. Nucleus

Answer: (A)

Electrons are the negatively charged particles that orbit the nucleus. In an atom, the nucleus contains protons (positive charge) and neutrons (no charge), while electrons move around outside the nucleus in regions called electron shells. The opposite charges attract, pulling electrons toward the nucleus but keeping them in orbit around it. This arrangement explains why the atom has a negative charge overall balance when needed. Protons stay in the nucleus and are positively charged, neutrons are neutral and also in the nucleus, and the nucleus itself is the center—not something that orbits.
