Tetratomic :: Tetratomic (a.) Consisting of four atoms; having four atoms in the molecule, as phosphorus and arsenic..

Tribasic :: Tribasic (a.) Capable of neutralizing three molecules of a monacid base, or their equivalent; having three hydrogen atoms capable of replacement by basic elements on radicals; -- said of certain acids; thus, citric acid is a tribasic acid..

Microcrith :: Microcrith (n.) 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..

Dissociation :: Dissociation (n.) The process by which a compound body breaks up into simpler constituents; -- said particularly of the action of heat on gaseous or volatile substances; as, the dissociation of the sulphur molecules; the dissociation of ammonium chloride into hydrochloric acid and ammonia..

Molecular :: Molecular (a.) Pertaining to, connected with, produced by, or consisting of, molecules; as, molecular forces; molecular groups of atoms, etc..

Undecane :: Undecane (n.) A liquid hydrocarbon, C11H24, of the methane series, found in petroleum; -- so called from its containing eleven carbon atoms in the molecule..

Monatomic :: Monatomic (adv.) Consisting of, or containing, one atom; as, the molecule of mercury is monatomic..

Tetryl :: Tetryl (n.) Butyl; -- so called from the four carbon atoms in the molecule.

Substitute :: Substituent (n.) Any atom, group, or radical substituted for another, or entering a molecule in place of some other part which is removed..

Equivalent :: Equivalent (n.) A combining unit, whether an atom, a radical, or a molecule; as, in acid salt two or more equivalents of acid unite with one or more equivalents of base..

Bisulphide :: Bisulphide (n.) A sulphide having two atoms of sulphur in the molecule; a disulphide, as in iron pyrites, FeS2; -- less frequently called bisulphuret..

Pentoxide :: Pentoxide (n.) An oxide containing five atoms of oxygen in each molecule; as, phosphorus pentoxide, P2O5..

Molecule :: Molecule (n.) A group of atoms so united and combined by chemical affinity that they form a complete, integrated whole, being the smallest portion of any particular compound that can exist in a free state; as, a molecule of water consists of two atoms of hydrogen and one of oxygen. Cf. Atom..

Wave :: Wave (v. i.) A vibration propagated from particle to particle through a body or elastic medium, as in the transmission of sound; an assemblage of vibrating molecules in all phases of a vibration, with no phase repeated; a wave of vibration; an undulation. See Undulation..

Pentane :: Pentane (n.) Any one of the three metameric hydrocarbons, C5H12, of the methane or paraffin series. They are colorless, volatile liquids, two of which occur in petroleum. So called because of the five carbon atoms in the molecule..

Pentabasic :: Pentabasic (a.) 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.

Polychloride :: Polychloride (n.) A chloride containing more than one atom of chlorine in the molecule.

Polysilicic :: Polysilicic (a.) Of or pertaining to compounds formed by the condensation of two or more molecules of silicic acid.

Ternary :: Ternary (a.) Containing, or consisting of, three different parts, as elements, atoms, groups, or radicals, which are regarded as having different functions or relations in the molecule; thus, sodic hydroxide, NaOH, is a ternary compound..
