🔑 Key Concepts & Definitions

  • Atom: The smallest unit of an element that retains its chemical properties; composed of subatomic particles.
  • Proton: A positively charged subatomic particle located in the nucleus; defines the atomic number.
  • Neutron: A neutral (no charge) subatomic particle in the nucleus; contributes to atomic mass and stability.
  • Electron: A negatively charged subatomic particle orbiting the nucleus; involved in chemical bonding and reactions.
  • Atomic Number (Z): The number of protons in an atom's nucleus; identifies the element.
  • Mass Number (A): The total number of protons and neutrons in an atom; determines isotope identity.
