My question is just a quick one. I have an element project due at the end of the week and have just one piece of data missing. I'm to make an ad for a random element, (Lu) and I need to know the price-per-pound of the pure element. I have checked four sites and tried my browser's search engine, but I'm not coming up wth anything other than Super-Vita-Health-Junk (Are they allowed to put Lu in vitamins?). Thanks!
