Hunting For Elements
Over seventy years ago, mankind completed an ambitious map unlike any other - the periodic table of the elements – which contained and organized all the known elements at the time. Like other maps, the period table has changed as the geography of its contents - especially since 1941, when researchers at the University of California, Berkeley produced the first man-made element… plutonium. Many more elements have been added to the list, and efforts to create and research new ones continues –here to discuss this difficult scientific quest is Rob Dunn, biologist and writer in the Department of Biology at North Carolina State University. He recently wrote about element hunting for National Geographic.
