When trying to decide how to tag Why would tellurium have been a good gasoline additive if it wasn't so smelly, and why is it so smelly? I discovered that there are many metal-related tags:
- metal 542 questions
For questions about metals in general and their physical or chemical properties. For characteristic properties and reactions of d and f block metals specifically, use the [transition-metals] and [rare-earth-elements] tags respectively instead.
- noble-metals 7 questions
The noble-metals tag has no usage guidance, can you help us create it?
- transition-metals 520 questions
For questions about the characteristic physical properties, chemical reactions, etc. of d-block elements, group 3-12, or their compounds. Do not use this tag if your questions is about general properties of metals, use [metal] instead. Also see [rare-earth-elements].
- organometallic-compounds 200 questions
For questions relating to organic compounds which contain a bond between a carbon atom and a metal.
- alkali-metals 73 questions
For questions about the alkali metals (group 1), their compounds, and their physical and chemical properties. For questions specifically about hydrogen, use tag [hydrogen] instead.
- alkaline-earth-metals 23 questions
For questions about the alkaline earth metals (group 2), their compounds, and their physical and chemical properties.
- organotransition-metal-chemistry 12 questions
For questions about the use of transition metals in organic synthesis.
Wikipedia's Tellurium begins:
Tellurium is a chemical element with the symbol Te and atomic number 52. It is a brittle, mildly toxic, rare, silver-white metalloid.
and that article begins:
A metalloid is a type of chemical element which has a preponderance of properties in between, or that are a mixture of, those of metals and nonmetals. There is no standard definition of a metalloid and no complete agreement on which elements are metalloids. Despite the lack of specificity, the term remains in use in the literature of chemistry.
The six commonly recognised metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium. Five elements are less frequently so classified: carbon, aluminium, selenium, polonium, and astatine. On a standard periodic table, all eleven elements are in a diagonal region of the p-block extending from boron at the upper left to astatine at lower right. Some periodic tables include a dividing line between metals and nonmetals, and the metalloids may be found close to this line.
sulfur has a tag, but there is no separate tag for silicon or germanium but there is a semiconductors for them.
I'm not sure of a pattern or plan, so I'll just as:
Question: Would a [metalloid] and/or [tellurium] tag be appropriate for the site, and /or for my question about tellurium?
