Dextrorotatory

Refers to an optically active substance that rotates the plane of plane polarized light clockwise, also called dextro.

Limiting Reactant

Substance that stoichiometrically limits the amount of product(s) that can be formed.

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.

Intermolecular Forces

Forces between individual particles (atoms, molecules, ions) of a substance.

Reaction Ratio

The relative amounts of reactants and products involved in a reaction, maybe the ratio of moles. millimoles, or masses.

 

xenon

A heavy, colorless, chemically inactive, monatomic gaseous element used for filling radio, television, and luminescent tubes. Symbol: Xe, at. wt.: 131.30, at. no.: 54.

Mother Nuclide

Nuclide that undergoes nuclear decay.

Sigma Bonds

Bonds resulting from the head-on overlap of atomic orbitals, in which the region of electron sharing is along and (cylindrically) symmetrical to the imaginary line connecting the bonded atoms.

Aldehyde

Compound in which an alkyl or aryl group and a hydrogen atom are attached to a carbonyl group and a hydrogen atom are attached to a carbonyl group, general formula, O-R-C-H

 

Valence Electrons
