formal charge

Front

# of valence electrons - # dots - # lines

Back

dipole

Front

creation of opposite charges at either end of the molecule

Back

bond strength

Front

Equal to the potential energy of a bond; the amount of energy required to break a bond.

Back

Dative covalent bond

Front

A shared pair of electrons in which the bonded pair has been provided by one of the bonding atoms only; also called a coordinate bond.

Back

ionic lattice

Front

repeating pattern of positive and negative ions forming an ionic compound

Back

Hybridization

Front

the mixing of several atomic orbitals to form the same total number of equivalent hybrid orbitals for bonding

Back

entropy

Front

a measure of the disorder of a system

Back

isomers

Front

Compounds with the same formula but different structures.

Back

ionic bonding

Front

transfer of electrons to form ions.

Back

pi bond

Front

a bond that is formed when parallel orbitals overlap to share electrons.

Back

Resonance

Front

the bonding in molecules or ions that cannot be correctly represented by a single Lewis structure

Back

sigma bond

Front

a single covalent bond that is formed when an electron pair is shared by the direct overlap of bonding orbitals. (strongest)

Back

Dimer

Front

a molecule or molecular complex consisting of two identical molecules linked together.

Back

non-polar covalent

Front

A non-polar covalent bond is a covalent bond in which the electrons are shared equally between the atoms.

Back

Interstitial alloy

Front

a mixture formed when small atoms fill holes in a metallic crystal

Back

Alloy

Front

A mixture of two or more metals

Back

substitutional alloy

Front

has atoms of the original metallic solid replaced by other metal atoms of similar size

Back

polar covalent

Front

a type of bond that forms when electrons are not shared equally

Back

bond length

Front

the distance between two bonded atoms at their minimum potential energy, that is, the average distance between two bonded atoms

Back

VSEPR

Front

Valence Shell Electron Pair Repulsion

Back

hydration

Front

polar water molecules are attracted to oppositely charged ions and penetrate the lattice energy attaching themselves to the ions.
