Actinides
Elements 89 to 103 (between lawrencium and actinium) on the periodic table. Only the first four have been found in nature in appreciable amounts. The remainder have been produced synthetically.
Saponification
Hydrolysis of esters in the presence of strong soluable bases.
Heterogeneous Catalyst
A catalyst that exists in a different phase (solid, liquid or gas) from the reactants, a contact catalyst.
Percent Composition
The mass percent of each element in a compound.
Formal Charge
A method of counting electrons in a covalently bonded molecule or ion, counts bonding electrons as though they were equally shared between the two atoms.
Bond Order
Half the numbers of electrons in bonding orbitals minus half the number of electrons in antibonding orbitals. Bond order gives an indication to the stability of a bond. Also defined as the difference between the number of bonding electrons and antibonding electrons divided by two.
High Spin Complex
Crystal field designation for an outer orbital complex, all t2g and eg orbitals are singly occupied before any pairing occurs.
Kinetic-molecular Theory
A theory, that attempts to explain macroscopic observations on gases in microscopic observations on gases in microscopic observations on gases in microscopic or molecular terms.
Exothermicity
The release of heat by a system as a process occurs.
Tetrahedral
A term used to describe molecules and polyatomic ions that have one atom in center and four atoms at the corners of a tetrahedron.
