Topic 4. The Nucleus

Key elements
The basic structure of an atom comprises a small central nucleus consisting of protons and neutrons (nucleons) surrounded by electrons. Isotopes are atoms of the same element that have different mass numbers. (chemically identical, physically different) Nucleus is held together by the Strong Force Color force holds quarks together creating baryons Nuclear force holds baryons together creating atomic nuclei Lectures Lecture - The Nucleus Videos Science Asylum, What Does An Atom REALLY Look Like?
