In the 5th edition of Inorganic Chemistry by Catherine Housecroft there's a mention (chapter 14.1) that IUPAC recommends using the term 'semi-metal' over 'metalloid'. I couldn't find the particular source but for example in https://iupac.qmul.ac.uk/BlueBook/P1.html the name semi-metal is used. Could someone look into this matter? It seems quite important 188.147.108.79 (talk) 18:07, 23 July 2023 (UTC)
Referring to metalloids as semimetals is discouraged as the term semimetal has a different meaning in physics than in chemistry. In physics, it refers to a specific kind of electronic band structure of a substance. In this context, only arsenic and antimony are semimetals, and commonly recognised as metalloids.
While the International Union of Pure and Applied Chemistry previously recommended abandoning the term metalloid, and using the term semimetal instead the most recent IUPAC publications on nomenclature and terminology do not include any recommendations on the usage of the terms metalloid or semimetal.
