Chemical element the elements, including consideration of their general physical and chemical properties, their states of matter under familiar conditions, their melting and boiling points, their densities, their crystal structures as solids, and their origins. Several terms are commonly used to characterize the general physical and chemical properties of the chemical elements. A first distinction is between metals, which readily conduct electricity, nonmetals, which do not, and a small group, (the "metalloids"), having intermediate properties and often behaving as semiconductors. A more refined classification is often shown in colored presentations of the periodic table. This system restricts the terms "metal" and "nonmetal"
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 environment and led to the destruction of various homes, cities, and even entire countries. Researchers discovered that the vanishing elements drained into a planet called Nega Earth, located in another dimension. Element dematerialization was occurring rapidly; thus, to save Earth, three special pre-teens picked by the space colony government formed the Element Hunters. Their job was to transport themselves to Nega-Earth to battle monsters called Q-EXes and retrieve lost elements. However, out of
