Mother Nuclide

Nuclide that undergoes nuclear decay.

Method of Initial Rates

Method of determining the rate-law expression by carrying out a reaction with different initial concentrations and analyzing the resultant changes in initial rates.

K Capture

Absorption of a K shell (n=1) electron by a proton as it is converted to a neutron.

Coordination Sphere

The metal ion and its coordinating ligands but not any uncoordinated counter-ions.

Solubility Product Constant

Equilibrium constant that applies to the dissolution of a slightly soluble compound.

Supercritical Fluid

A substance at temperature above its critical temperature.

Hydride

A binary compound of hydrogen.

 

Adhesive Forces

Forces of attraction between a liquid and another surface.

Dissociation Constant

Equilibrium constant that applies to the dissociation of a comples ion into a simple ion and coordinating species (ligands).

Silicones

Polymeric organosilicon compounds, contain individual or cross-linked Si-O chains or rings in which some oxygens of SiO4 tetrahedra are replaced by other groups.

High Spin Complex

Crystal field designation for an outer orbital complex, all t2g and eg orbitals are singly occupied before any pairing occurs.

Nuclear Binding Energy

Energy equivalent of the mass deficiency, energy released in the formation of an atom from the subatomic particles.

 

Nuclear Reaction

Involves a change in the composition of a nucleus and can evolve or absorb an extraordinarily large amount of energy.

Ligand

A Lewis base in a coordination compound.

Suspension

A heterogeneous mixture in which solute-like particles settle out of solvent-like phase some time after their introduction.

Law of Combining Volumes (Gay-Lussac's Law)

At constant temperature and pressure, the volumes of reacting gases (and any gaseous products) can be expressed as ratios of small whole numbers.

 

Conformations

Structures of a compound that differ by the extent of rotation about a single bond.

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.

Saccharate

A compound formed by interaction of sucrose with a metallic oxide, usually lime, and useful in the purification of sugar.

 

Oxidation Numbers

Arbitrary numbers that can be used as mechanical aids in writing formulas and balancing equations, for single- atom ions they correspond to the charge on the ion, more electronegative atoms are assigned negative oxidation numbers (also called Oxidation states).
