VSEPR Theory
Electron pairs in the valence shell stay as far apart as possible allowing prediction of molecular shapes.
Resonance Structure
Different arrangements of electrons of the compound having a geometrical structure.
Unshared Pair
A non-bonding pair of electrons.
Lewis Structure
Diagram using dots to represent electrons.
Valence Electrons
Number of electrons in the outermost energy level.
Dipole
Molocule with both a positive and negative region.
Covelent Bonds
When atoms share one or more pairs of electrons.
Molecular Orbital
The probable region of an electrons location around a molecule.
Polar Compound
A molecule where the shared electrons are held more closely by one atom yielding a positive and negative end.
Ionic Bond
The bond between a cation and an anion to form a compund.
Hydrogen Bond
Intermolecular attraction between a H of a molecule and a charged region.
Double Bond
Two atoms that share four electrons.
