摘要

本文提出了一种新的化学标准来区分金属、非金属和类金属元素，该标准基于化合物中含有一个或多个双电子供体L配体的比例，其中L是根据共价键分类方法中的等效中性类形式定义的。这些比例是通过最近公布的Chemdex数据库的数据挖掘计算出来的。根据这一标准得出的结论与基于元素电负性和气相原子的摩尔折射率与凝聚态摩尔体积之比的类金属分类进行了比较。

A Chemical Criterion to Distinguish Between Metals, Nonmetals, and Metalloids Based on Coordinated Ligands

A new chemical criterion is proposed to differentiate between elements classified as metals, nonmetals, and metalloids based on the proportion of their compounds that incorporate one or more two-electron donor L ligands where L is defined according to the Equivalent Neutral Class formalism within the Covalent Bond Classification methodology. These proportions have been calculated through data mining of the recently published Chemdex database. Conclusions according to this criterion are compared to metalloid classifications based on element electronegativities and the ratio of the molar refractivity of gas phase atoms to the molar volume in the condensed state.

期刊介绍： The Journal of Chemical Education is the official journal of the Division of Chemical Education of the American Chemical Society, co-published with the American Chemical Society Publications Division. Launched in 1924, the Journal of Chemical Education is the world’s premier chemical education journal. The Journal publishes peer-reviewed articles and related information as a resource to those in the field of chemical education and to those institutions that serve them. JCE typically addresses chemical content, activities, laboratory experiments, instructional methods, and pedagogies. The Journal serves as a means of communication among people across the world who are interested in the teaching and learning of chemistry. This includes instructors of chemistry from middle school through graduate school, professional staff who support these teaching activities, as well as some scientists in commerce, industry, and government.
