Which of the following subatomic particles is one of the components that make up atoms of matter?

• A. Proton
• B. Neutron
• C. Electron
• D. Quark

Answer: (C)

The subatomic particle that is considered a component of atoms and is chiefly relevant to atoms of matter is the electron. Electrons are negatively charged particles that orbit the nucleus of an atom, which is made up of protons and neutrons. Their arrangement and behavior are crucial because they determine the chemical properties of an element and how it interacts with other atoms.

While protons and neutrons also play vital roles within the nucleus of an atom—protons contributing to the identity of the element and neutrons adding to the atomic mass—electrons are particularly significant in the context of chemical bonding and reactions.

Quarks, although critical as constituents of protons and neutrons, are not direct components of atoms in the way that electrons are, as they combine to form protons and neutrons rather than existing independently in atomic structure. Therefore, identifying electrons as an integral part of atoms aligns with an understanding of atomic structure and its implications in chemistry and physics.
