Chemical element chemical bonds, they form chemical compounds. Only a minority of elements are found uncombined as relatively pure minerals. Among the more common of such native elements are copper, silver, gold, carbon (as coal, graphite, or diamonds), and sulfur. All but a few of the most inert elements, such as noble gases and noble metals, are usually found on Earth in chemically combined form, as chemical compounds. While about 32 of the chemical elements occur on Earth in native uncombined forms, most of these occur as mixtures. For example, atmospheric air is primarily a mixture of nitrogen, oxygen, and argon, and
Element Hunters their own concerns, Ren, Chiara, and Homi, three average middle school students from Earth, banded together to also become Element Hunters. With the help of Professor Aimee Carr and Juno, they are able to help save their own planet. The team made up of children who have the ability to go to "Nega Earth." They are taken from Earth early in their lives and trained in the Space Colony to become Element Hunters. Element Hunters In the year 2029, chemical elements such as oxygen, carbon, gold, molybdenum, and cobalt were continually disappearing from Earth. These disappearing elements ultimately disrupted the
