Atomic Architecture and the Periodic Table · Atomic Structure

Subatomic Particles and Isotopes

Examination of protons, neutrons, and electrons and how their ratios define elemental identity and stability.

Key Questions

  2. 2What evidence do we have for the existence of isotopes in nature?
  3. 3How does the balance of subatomic forces prevent an atom from collapsing?
