      Atoms
    • What are ions?
      Particles with charges
    • What is the difference between physical and chemical properties?
      • Physical properties: No change in composition occurs during measurement.
      • Chemical properties: A change in composition occurs during measurement.
    • What happens to extensive properties when the amount of matter changes?
      They change their value
    • What happens to intensive properties when the amount of matter changes?
      They do not change their value
    • What are the two main categories of substances?
      • Pure substances
      • Mixtures
    • What distinguishes pure substances from mixtures?
      Pure substances are composed of only one component, while mixtures are composed of several components.
