Lj. 24K Gold is an Element (Au) but anything that below that like 10K or 18K is a mixture because it is physically separated from it's alloy. It is mixed with copper or silver.
Marina, you are the first person to 5 points. Congratulations. Keep it up. You may apply 2 points to this take home exam, or to a free homework. Let me know in school on wednesday.
