Not a substanceAn atom is a particle of matter that characterizes a chemical element123. It is the smallest part of ordinary matter123. Atoms contain electrons, neutrons, and protons4123. Each element is defined by the number of protons in its nucleus4. An element is a pure substance made entirely of one type of atom153. Therefore, an atom is not a substance, but a building block of matter that cannot be divided into small pieces by any chemical process3.Learn more:✕This summary was generated using AI based on multiple online sources.
