Iron physical or chemical
WebIron is a metal and all metals have a type of bonding called metallic bonding which is different from covalent or ionic bonding. In metallic bonding the outer shells of adjacent atoms overlap, and the outer shell electrons are free to move through the lattice. The metal consists of metal cations and a balancing number of these ‘free’ electrons. WebThe underlying equation underlying rusting is Fe + O2 + H2O -> Fe2O3 and because a new substance is created, this is indeed a chemical change. Not only is rust a new substance, its properties are actually quite different from regular iron. Rust is essentially iron oxide or sometimes iron alloys. Further, because the reaction is irreversible ...
