• Why Is Ice Slippery? The Thin Liquid Layer Explained
  Ice is slippery because a thin, disordered layer of water on its surface acts like a liquid even below freezing, since surface molecules have missing bonds.
• Chemical Bonding
  The forces that hold atoms together in molecules and crystals: ionic, covalent, and metallic bonds determined by electronegativity differences.
• Functional Groups
  The characteristic atom groupings in organic molecules that determine their chemical behavior and reactivity.
