What are the negatively charged particles that circle the nucleus of an atom called?

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

Answer: (C)

The particles that are negatively charged and circle the nucleus of an atom are known as electrons. Electrons are fundamental components of atoms and play a crucial role in chemical bonding and reactions. They occupy various energy levels or orbitals around the nucleus, which contains positively charged protons and neutral neutrons.

In an atom, electrons balance the positive charge of protons, contributing to the overall charge neutrality of the atom in its uncharged state. Their movement and arrangement in these energy levels determine the chemical properties of the element, such as its reactivity and the types of bonds it can form with other atoms. Understanding the role of electrons is essential for grasping the basics of atomic structure and chemistry as a whole.
