May 20, 2024 · Learn about the basic building block of matter and chemistry, its subatomic particles, and its chemical properties. Explore the history of atomic theory and the periodic table of elements.
An atom consists of a nucleus of protons and generally neutrons, surrounded by an electromagnetically bound swarm of electrons. The chemical elements are distinguished from each other by the number of protons that are in their atoms. For example, any atom that contains 11 protons is sodium, and any atom that contains 29 protons is copper.
