Isomer \I"so*mer\ ([imac]"s[-o]*m[~e]r), n. [See Isomeric.] (Chem.) A compound which is isomeric with another body or compound; a compound having the same chemical composition as another compound; a member of an isomeric series.
Note: An isomer may be a structural isomer, in which some of the atoms are bonded to different atoms (as in CH3.CH2.NH2 and CH3.NH.CH3), or an optical isomer, in which the number and types of chemical bonds are identical, but the arrangement of the atoms in three-dimensional space is different; the latter are also called stereoisomers.

Wikipedia
An isomer (; from Greek ἰσομερής, isomerès; isos = "equal", méros = "part") is a molecule with the same molecular formula as another molecule, but with a different chemical structure. That is, isomers contain the same number of atoms of each element, but have different arrangements of their atoms. Isomers do not necessarily share similar properties, unless they also have the same functional groups. There are two main forms of isomerism ( or ): structural isomerism (or constitutional isomerism) and stereoisomerism (or spatial isomerism).
Isomer (Greek isos = "equal", méros = "part") is an element of transverse body articulation of the bilateral fossil animals of the Phylum Proarticulata from the Ediacaran (Vendian) period. This term has been proposed by Andrey Yu. Ivantsov, a Russian paleontologist from the Laboratory of the Precambrian organisms, Paleontological Institute, Russian Academy of Sciences.

It may well be -- I have believed so ever since I was fourteen years old -- that the elements are all isomers, differentiated by geometrical structure, electrical charge, or otherwise in precisely the same way as ozone from oxygen, red from yellow phosphorous, dextrose from ~laevulose, and a paraffin from a benzene of identical empirical formula.
