Thermonuclear Energy

The energy stored in the nucleus of an atom and released through fission, fusion, or radioactivity. In these processes a small amount of mass is converted to energy according to the relationship E = mc2, where E is energy, m is mass, and c is the speed of light.

Condensation

Liquefaction of vapor.

Flammable

A liquid as defined by NFPD and DOT as having a flash point below 37.8°C (100°F).

Element

A substance that cannot be decomposed into simpler substances by chemical means.

Differential Scanning Calorimetry (DSC)

A technique for measuring the temperature, direction, and magnitude of thermal transitions in a sample material by heating/cooling and comparing the amount of energy required to maintain its rate of temperature increase or decrease with an inert reference material under similar conditions.

Electromotive Series

The relative order of tendencies for elements and their simple ions to act as oxidizing or reducing agents, also called the activity series.

Nonbonding Orbital

A molecular orbital derived only from an atomic orbital of one atom, lends neither stability nor instability to a molecule or ion when populated with electrons.

Outer Orbital Complex

Valence bond designation for a complex in which the metal ion utilizes d orbitals in the outermost (occupied) shell in hybridization.

Supercritical Fluid

A substance at temperature above its critical temperature.

Double Bond

Covalent bond resulting from the sharing of four electrons (two pairs) between two atoms.
