Isomer

Briefly, two compounds are said to be isomeric if they are composed of the same elements in the same proportion by weight but have different chemical and physical properties.

Isomer

[Proarticulata] 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, Paleontol...

Isomer

In chemistry, isomers (z; from Greek ἰσομερής, isomerès; isos = `equal`, méros = `part`) are molecules with the same molecular formula but different chemical structures. That is, isomers contain the same number of atoms of each element, but have different arrangements of their atoms in space. Isomers do not necessarily share similar...
