Lern More About Molecule

Polysilicic :: Polysilicic (a.) Of or pertaining to compounds formed by the condensation of two or more molecules of silicic acid.
Residue :: Residue (n.) That which remains of a molecule after the removal of a portion of its constituents; hence, an atom or group regarded as a portion of a molecule; -- used as nearly equivalent to radical, but in a more general sense..
Tetrol :: Tetrol (n.) A hypothetical hydrocarbon, C4H4, analogous to benzene; -- so called from the four carbon atoms in the molecule..
Pentachloride :: Pentachloride (n.) A chloride having five atoms of chlorine in each molecule.
Trikosane :: Trikosane (n.) A hydrocarbon, C23H48, of the methane series, resembling paraffin; -- so called because it has twenty-three atoms of carbon in the molecule..
Atom :: Atom (n.) An ultimate particle of matter not necessarily indivisible; a molecule.
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..
Disulphuric :: Disulphuric (a.) Applied to an acid having in each molecule two atoms of sulphur in the higher state of oxidation.
Stearolic :: Stearin (n.) One of the constituents of animal fats and also of some vegetable fats, as the butter of cacao. It is especially characterized by its solidity, so that when present in considerable quantity it materially increases the hardness, or raises the melting point, of the fat, as in mutton tallow. Chemically, it is a compound of glyceryl with three molecules of stearic acid, and hence is technically called tristearin, or glyceryl tristearate..
Atom :: Atom (n.) A constituent particle of matter, or a molecule supposed to be made up of subordinate particles..
Pentoxide :: Pentoxide (n.) An oxide containing five atoms of oxygen in each molecule; as, phosphorus pentoxide, P2O5..
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.
Molecularity :: Molecularity (n.) The state of consisting of molecules; the state or quality of being molecular.
Quartenylic :: Quartenylic (a.) Pertaining to, or designating, an acid of the acrylic acid series, metameric with crotonic acid, and obtained as a colorless liquid; -- so called from having four carbon atoms in the molecule. Called also isocrotonic acid..
Hendecane :: Hendecane (n.) A hydrocarbon, C11H24, of the paraffin series; -- so called because it has eleven atoms of carbon in each molecule. Called also endecane, undecane..
Diselenide :: Diselenide (n.) A selenide containing two atoms of selenium in each molecule.
Palmitin :: Palmitin (n.) A solid crystallizable fat, found abundantly in animals and in vegetables. It occurs mixed with stearin and olein in the fat of animal tissues, with olein and butyrin in butter, 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..
Trisnitrate :: Trisnitrate (n.) A nitrate formed from three molecules of nitric acid; also, less properly, applied to certain basic nitrates; as, trisnitrate of bismuth..
Atomicity :: Atomicity (n.) Degree of atomic attraction; equivalence; valence; also (a later use) the number of atoms in an elementary molecule. See Valence.
Quartane :: Quartane (n.) Butane, each molecule of which has four carbon atoms..
