Century Dictionary and Cyclopedia
- n. The science of the composition of material things and the changes which they undergo in consequence of changes in their ultimate composition. It regards all substances as made up of atoms (see
atom) which are indivisible and have certain unchanging properties. An elementary substance consists of groups of chemically united atoms of the same kind; a compound substance, of groups of chemically united atoms of two or more different kinds. All compound substances, and most elementary ones, consist of definite groups of chemically united atoms which are called molecules. Each molecule has exactly the same chemical composition and properties as the whole mass of the substance, and is the smallest mass into which the substance can be divided without losing its identity. The laws, causes, and effects of changes in the kind, and the number and arrangement, of atoms within the molecule are the subject-matter of the science. See chemical.
- n. Same as chemiatry.
- n. uncountable The branch of natural science that deals with the composition and constitution of substances and the changes that they undergo as a consequence of alterations in the constitution of their molecules.
- n. countable An application of chemical theory and method to a particular substance.
- n. informal The mutual attraction between two people; rapport.
GNU Webster's 1913
- n. That branch of science which treats of the composition of substances, and of the changes which they undergo in consequence of alterations in the constitution of the molecules, which depend upon variations of the number, kind, or mode of arrangement, of the constituent atoms. These atoms are not assumed to be indivisible, but merely the finest grade of subdivision hitherto attained. Chemistry deals with the changes in the composition and constitution of molecules. See atom, molecule.
- n. An application of chemical theory and method to the consideration of some particular subject.
- n. A treatise on chemistry.
- n. the science of matter; the branch of the natural sciences dealing with the composition of substances and their properties and reactions
