A charged species created by the gain or loss of an electron from an atom
or neutral molecule.
A bond that results from electrostatic attraction between oppositely charged
ions. The cation is
positively charged, while the anion is negatively charged.
A regularly repeating three-dimensional array of atoms,
A description of a covalent bond whereby electrons are represented by dots
bond is represented
by placing a line between the two atoms in that bond. Only valence

A nonbonding pair of electrons.
A chemical species containing a covalent bond.
The three dimensional structure and orientation of the atoms, bonds, and
pairs in a
Eight electrons. For atoms other than H, the valence shell is filled with
electrons. A filled
valence gives the molecule a noble gas configuration and renders it stable.
An electron configuration with a partially filled valence shell.
One of several Lewis structures whose average represents an accurate

properly represented by one simple Lewis structure.
An electron located in the valence shell.
The orbitals with the highest occupied
principle quantum number.
Valence Shell Electron Pair Repulsion Theory
A theory used to predict bonding geometries that states that electron pairs
be distributed about the
central atom to minimize electron pair repulsions.
