Key Concepts & Definitions

  • Matter: Anything that has mass and occupies space. It exists in solid, liquid, or gas states.
  • Atom: The smallest unit of an element that retains its chemical properties; composed of protons, neutrons, and electrons.
  • Molecule: Two or more atoms chemically bonded together, representing the smallest unit of a compound.
  • Element: A pure substance consisting of only one type of atom, characterized by its atomic number.
  • Compound: A substance formed when two or more elements are chemically bonded; can be molecular (covalent bonds) or ionic (electrostatic attraction).
  • Ion: An atom or molecule with a net electric charge, classified as monoatomic (single atom) or polyatomic (group of atoms).
