INTRODUCTION TO
CHEMICAL BONDING
Terms
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.
