question

do you capitalize elements of the periodic table
passage · full text (1,222 characters)
In former versions of the IUPAC recommendations, names were written with a capital initial letter. This practice has been abandoned in later publications. The names of chemical compounds and chemical elements when written out, are common nouns in English, rather than proper nouns. They are capitalized at the beginning of a sentence or title, but not elsewhere. Note that for chemical elements this applies to the word only and not the chemical symbol, which is always capitalized. Both rules remain even with chemical elements derived from proper names which would otherwise be capitalized, in keeping with IUPAC policy to differentiate proper names from things named after proper names. Thus, it is californium but the symbol is Cf, and einsteinium, but symbol Es. Note that names for odd or rare chemicals are uncapitalized like common ones, and thus uranium and plutonium (symbols U and Pu) should be uncapitalized like carbon or iron (symbols C and Fe). This rule (full name uncapitalized but symbol capitalized) applies also to isotopes and nuclides, when completely written out: thus C but carbon-14. (The element mercury is uncapitalized, but of course the planet and god Mercury remain capitalized proper nouns).
