Metal dioxides, on the other hand, are pervasive, such as MnO 2 and rutile (TiO 2). Well characterized examples of transition metal peroxides include the d 10 metal cations: zinc peroxide (ZnO 2), two polymorphs (both explosive) of mercury peroxide (HgO 2), and cadmium peroxide (CdO 2). Peroxide is a common ligand in metal complexes.
Hace 5 horas · Individual lists share common ground, with variations occurring at the margins. The elements most often regarded as metalloids are boron, silicon, germanium, arsenic, antimony and tellurium. [n 1] Other sources may subtract from this list, add a varying number of other elements, or both.
Hace 5 horas · e. A metalloid is a type of chemical element which has a preponderance of properties in between, or that are a mixture of, those of metals and nonmetals. There is no standard definition of a metalloid and no complete agreement on which elements are metalloids. Despite the lack of specificity, the term remains in use in the literature of chemistry.
Hace 5 horas · Nonmetals in chemistry or non-metallic elements are chemical elements that have high electronegativity and mostly lack distinctive metallic properties. They range from colorless gases like hydrogen to shiny crystals like iodine. Physically, they are usually lighter (less dense) than metals and are often poor conductors of heat and electricity.
Hace 1 día · Platinum is a member of the platinum group of elements and group 10 of the periodic table of elements. It has six naturally occurring isotopes. It is one of the rarer elements in Earth's crust, with an average abundance of approximately 5 μg /kg. It occurs in some nickel and copper ores along with some native deposits, mostly in South Africa ...
