Flammable
A liquid as defined by NFPD and DOT as having a flash point below 37.8°C (100°F).
High Spin Complex
Crystal field designation for an outer orbital complex, all t2g and eg orbitals are singly occupied before any pairing occurs.
Gas of rotten eggs
If you happen to break a rotten egg, then you know the smell of hydrogen sulfide, because the stench of the spoiled egg depends on of its presence in rotting protein substances.
Composition Stoichiometry
Descibes the quantitative (mass) relationships among elements in compounds.
Electronic Transition
The transfer of an electron from one energy level to another.
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.
Double Bond
Covalent bond resulting from the sharing of four electrons (two pairs) between two atoms.
Binary Acid
A binary compound in which H is bonded to one or more of the more electronegative nonmetals.
