35. Review Sheet
Structural Formulas (Lewis Structures: structural formula that used dots and lines to describe bonding.
Molecular Geometry: Shape of a molecule based on number of bonded atoms and lone pairs on an atom
Ball and Stick Model: three dimensional physical model of molecular shape.
VSEPR Theory: In a small molecule, the pairs of valence electrons are arranged as far apart from each other as possible.
Bonded Pair: electrons in a bond between two atoms
Unbonded Pair: electrons not involved in a bond (lone pair)
Substituent: a bonded or unbonded pair on an atom
Bond Angle: Angle formed by neighboring atoms

36. Review Sheet Hybrid Orbital: a mixture (or blended) orbital
Polarity: unequal sharing of electrons in a bond
Bond Polarity: direction of the unequal sharing of electrons in a bond
Molecule Polarity: overall direction of polarity in a molecule
Dipole: a polar molecule (one that has a positive end and a negative end)
Intermolecular Force: a force of attraction that exists between neighboring molecules because of their polarity
Dipole-Dipole Attraction: Attraction between neighboring dipoles
Hydrogen Bond: strong dipole bond between the hydrogen atom of a molecule and a highly electronegative atom of another molecule such as F, O or N.
