, ect. Specific gravity 13.6. Symbol Hg (Hydrargyrum). Atomic weight 199.8. Mercury has a molecule which consists of only one atom. It was named by the alchemists after the god Mercury, and designated by his symbol, mercury.

A theoretical aggregation of molecules constituting a structural particle of protoplasm, capable of increase or diminution without change in chemical nature.

The weight of the half hydrogen molecule, or of the hydrogen atom, taken as the standard in comparing the atomic weights of the elements; thus, an atom of oxygen weighs sixteen microcriths. See Crith. J. P. Cooke.

of matter; -- said of the properties or motions of masses, as distinguished from those of molecules or atoms. Carpenter.

Pertaining to, connected with, produced by, or consisting of, molecules; as, molecular forces; molecular groups of atoms, etc. Molecular attraction (Phys.), attraction acting between the molecules of bodies, and at insensible distances. -- Molecular weight (Chem.), the weight of a molecule of any gas or vapor as compa…

The state of consisting of molecules; the state or quality of being molecular.

With molecules; in the manner of molecules. W. R. Grove.

Consisting of, or containing, one atom; as, the molecule of mercury is monatomic.

An oxide containing one atom of oxygen in each molecule; as, barium monoxide.

Any one of a series of complex nitrogenous substances regarded as derived from one molecule of urea; as, alloxan is a monureid. [Written also monureide.]

arbons C9H20 of the paraffin series; -- so called because of the nine carbon atoms in the molecule. Normal nonane is a colorless volatile liquid, an ingredient of ordinary kerosene.

ries, a white waxy substance, C19H40; -- so called from the number of carbon atoms in the molecule.

em.), borax obtained from a saturated solution in octahedral crystals, which contain five molecules of water of crystallization; distinguished from common or prismatic borax. -- Octahedral iron ore (Min.), magnetite.

ts, especially at 30-40° C. Chemically, olein is a glyceride of oleic acid; and, as three molecules of the acid are united to one molecule of glyceryl to form the fat, it is technically known as triolein. It is also called elain.

tter, with olein in olive oil, etc. Chemically, it is a glyceride of palmitic acid, three molecules of palmitic acid being united to one molecule of glyceryl, and hence it is technically called tripalmitin, or glyceryl tripalmitate.

Capable of uniting with five molecules of a monacid base; having five acid hydrogen atoms capable of substitution by a basic radical; -- said of certain acids.

A chloride having five atoms of chlorine in each molecule.

Capable of neutralizing, or combining with, five molecules of a monobasic acid; having five hydrogen atoms capable of substitution by acid residues; -- said of certain complex bases.

c., and obtained as a colorless liquid; -- so called from the fifteen carbon atoms in the molecule.

quids, two of which occur in petroleum. So called because of the five carbon atoms in the molecule.
