WebBending of iron: Physical. Explanation: Iron atoms don’t combine with different elements when iron bends. Metabolizing food: Chemical. Explanation: Molecules in food get broken down. For example, atoms from sugar get rearranged into carbon dioxide and water. Mixing sand and water: Physical. The water is still water and the sand is still sand. 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.
