metallic bonding

• metallic bonding occurs in metallic elements such as iron and copper and alloys such as stainless steel.
• metals have a giant structure in which electrons in the outer shell are delocalised.
• this produces a regular arrangement (lattice) of positive ions held together by electrostatic attraction to the delocalised electrons.
• a metallic bond is the attraction between the positive ions and the delocalised negatively charged electrons
