1/13
  • Molecular Polarity

    Influences physical and chemical properties due to unequal electron sharing.
  • Electronegativity

    A measure of an atom's ability to attract electrons in a bond.
  • Nonpolar Molecule

    A molecule with equal electron distribution, often hydrocarbons or perfect shapes.
  • Polar Molecule

    A molecule with uneven electron distribution, lacking a perfect shape.
  • Hydrocarbon

    A compound composed solely of carbon and hydrogen atoms.
  • Perfect Shape

    Molecular geometry with identical surrounding elements and no lone pairs.
  • Perfect Shape 1

    Central atom with identical surrounding elements and no lone pairs.
  • Perfect Shape 2

    Central atom with identical surrounding elements, linear or square planar.
  • Lone Pair

    A pair of valence electrons not shared with another atom.
  • Electron Group

    Either a surrounding element or a lone pair on the central atom.
  • Linear

    A molecular shape where atoms are arranged in a straight line.
  • Square Planar

    A molecular shape with atoms arranged in a square on a single plane.
  • Lewis Dot Structure

    A diagram showing the bonding between atoms and lone pairs of electrons.
