Together these account for perhaps a few hundred genes in many bacteria. Bacterial plasmids encode resistance systems for toxic metal and metalloid ions including Ag + AsO 2 - , AsO 4 3- , Cd 2+ , Co 2+ , CrO 4 2 , Cu 2+ , Hg 2+ , Ni 2+ , Pb 2+ , TeO 3 2 , TI + ...

THE unique role that gold plays in society is to a large extent related to the fact that it is the most noble of all metals: it is the least reactive metal towards atoms or molecules at the interface with a gas or a liquid. The inertness of gold does not reflect a general inability ...

This leads to the prediction of a stable, never before synthesized TaIrGe compound made of all-metal heavy atom compound. Laboratory synthesis then found it to be stable in the predicted crystal structure and p-type transparent conductor with a strong optical absorption peak at 3.36 eV and ...

句子 Thus when the series of elements was written so as to begin a new horizontal row with each alkali metal, elements of the same groups were automatically assembled in vertical columns in a periodic table of the elements. 问题 句子分析(俗称“长难句分析”)是训练提高基础阅读能力的有效手段。
Where are metals and nonmetals located on the periodic table? Is arsenic a metal, a nonmetal, or a metalloid? What other elements are in the same group on the periodic table as arsenic? What are the characteristics of metalloids? Which of the ele...
