ddhjx Posted April 27, 2012 Share Posted April 27, 2012 Hi everyone! I am an English learner and I would like to know how do people name intermetallic compounds. For example, Mg2Si is "magnesium silicide". Then what is the name of AlCu? How to add "-ide" to copper? Link to comment Share on other sites More sharing options...

This is an alloy, and technically you could change it's identity by varying the amounts of each metal in the alloy so you can't really treat it as a distinct molecule or stoichiometric salt.

ddhjx Posted April 28, 2012 Author Share Posted April 28, 2012 Thank you for replying. I know actually they don't form an anion. But in alloys I constantly meet something like "AlCu". Al "anion" is called "Aluminide". I didn't find anything for Cu. I just want to know how to read things like "AlCu". Neither the Al or Cu will actually form an anion so no atom gets the "-ide" designation.

ddhjx Posted April 28, 2012 Author Share Posted April 28, 2012 Thank you! Unexpectedly, it is Latin root + "-ide". I could comfortably read stuff like "AlCu" now, although wikipedia does not provide complete nomenclatures for every element.

Do you think that suggests that there are actual copper anions in the lattice? Or is that just a naming convention based on electonegativity?

John Cuthber Posted April 28, 2012 Share Posted April 28, 2012 I don't know about copper, but there are real gold compounds of that nature http://en.wikipedia.org/wiki/Caesium_auride http://www2.fkf.mpg.de/jansen/p150/english/aurides.html Link to comment Share on other sites More sharing options...
