Nuclear Reactors A nuclear reactor, formerly known as an atomic pile, is a device used to initiate and control a self-sustained nuclear chain reaction. Nuclear reactors are used at nuclear power Plants for electricity generation and in propulsion of ships. Heat from nuclear fission is passed to a working fluid (water or gas), which in … Read more
Metal In chemistry, a metal is an element that readily forms positive ions (cations) and has metallic Bonds. Metals are sometimes described as a lattice of positive ions surrounded by a cloud of delocalized electrons. The metals are one of the three groups of Elements as distinguished by their ionization and bonding properties, along … Read more
