A molecule of matter can be divided chemically into smaller particles called atoms. This concept is fundamental to chemistry, as a molecule is defined as a group of two or more atoms bonded together. When chemical reactions occur, these molecules can break down into individual atoms, which are the basic units of chemical elements. Atoms retain the unique properties of the elements they represent, such as hydrogen, oxygen, and carbon.

The other options pertain to subatomic particles or components of atoms rather than the breakdown of molecules. Electrons are negatively charged subatomic particles found in atoms, while protons are positively charged subatomic particles located in the nucleus of an atom. Nuclei refer to the central core of an atom containing protons and neutrons. Understanding the distinction between molecules and their atomic components is crucial for grasping the principles of chemistry and molecular structure.
