Anion  -  A negatively charged ion.
Bond  -  That which holds together atoms in molecules and ions in lattices.
Cation  -  A positively charged ion.
Coulomb's Law  -  A mathematical formula whose consequence is that negatively and positively charged particles attract each other and similarly charged species repel each other.
Covalent Bond  -  A bond that results from a sharing of electrons between nuclei.
Ion  -  A charged species created by the gain or loss of an electron from an atom or neutral molecule.
Ionic Bond  -  A bond that results from electrostatic attraction between oppositely charged ions. The cation is positively charged, while the anion is negatively charged.
Lattice  -  A regularly repeating three-dimensional array of atoms, molecules, or ions.
Molecular Orbital  -  A combination of atomic orbitals in molecular orbital theory that provides an orbital description of a molecule analogous to the atomic orbital description of atoms.
Molecular Orbital Theory  -  A description of bonding that combines atomic orbitals from each bondedatom to produce a set of molecular orbitals.
Molecule  -  A chemical species containing a covalent bond.
Valence Shell Electron Pair Repulsion Theory  -  A theory used to predict bonding geometries that states that electron pairs will be distributed about the central atom to minimize electron pair repulsions.
