Amino Acid
Compound containing both an amino and a carboxylic acid group.The --NH2 group.
Electronic Geometry
The geometric arrangement of orbitals containing the shared and unshared electron pairs surrounding the central atom of a molecule or polyatomic ion.
Crystal Field Stabilization Energy
A measure of the net energy of stabilization gained by a metal ion's nonbonding d electrons as a result of complex formation.
Capillary

Stereoisomers
Isomers that differ only in the way that atoms are oriented in space, consist of geometrical and optical isomers.
Mass Spectrometer
An instrument that measures the charge-to-mass ratio of charged particles.
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.
