🔑 Key Concepts & Definitions

  • Atom: The smallest unit of an element, composed of a nucleus and a surrounding cloud of electrons.
  • Nucleus: The central part of an atom containing protons (positively charged) and neutrons (neutral).
  • Proton (p⁺): A positively charged subatomic particle within the nucleus.
  • Neutron (n): A neutral subatomic particle within the nucleus.
  • Electron (e⁻): A negatively charged particle orbiting the nucleus in a cloud.
  • Ion: An atom that has gained or lost electrons, resulting in a net charge.
    • Cation: A positively charged ion, formed by losing electrons.
    • Anion: A negatively charged ion, formed by gaining electrons.
  • Atomic number (Z): The number of protons in an atom, defining the element.
  • Mass number (A): The total number of protons and neutrons in an atom’s nucleus.
