deuterozo61d

[ Gr.deuteros =second, and Eng. zooid (q. v.).] deut-hy-drog-u-rět, den-to-hy-drog-u-rět, 8. [Gr. deuteros=second; Eng. hydroguret (q. v.).] Chem.: A compound of two atoms of hydrogen with one of some other element. den-tō, pref. [Gr.deuteros=second.] Chem., .: In composition used to expre that two atoms of the substance named are combined with one or more of another. The proper use of the prefix deuto is to denote the second in order of the terms of any series: thus, in the several series of oxides FeO, Fe2O3; MnO, Mn2O3, MnO2; Mn2O3, PbO are, properly speaking, the deutoxides PbO, PbO, Pb2O3, PbO2, the compounds Fe2O3, the place of the compound in the series, not its of the respective metals, the deuto denoting simply atomic composition. But the prefix has often been confounded with bi- or di- , which properly refers to the constitution of the compound, as compared with that of the proto- or mono- compounds of the same series.
