Spelling of chemical names
Please don't change sulfur and sulfide to sulphur and sulphide in articles (as you did in these edits:, ). The English-language Wikipedia has no preferred national variety of English spelling. In general, if an article has been written in one variety of English (UK or U.S.), it is left that way unless there is a good reason to make a change. See Manual of Style for more details.

As well, sulfur/sulphur is something of a special case. As noted in Sulfur, IUPAC now recommends sulfur as the single universal spelling. This standard has been adopted by a number of UK institutions, including the Royal Society of Chemistry and the Qualifications and Curriculum Authority. Please don't update any more sulfurs.

On a side note, van der Waals – with the s – is a proper Dutch last name; it doesn't take an apostrophe in van der Waals force. Cheers, TenOfAllTrades(talk) 15:15, 10 February 2008 (UTC)
