Structure of metals
Structure and bonding in metals: Metals consist of giant structures of atoms arranged in a regular pattern. The electrons from the outer shell of the metal atoms are delocalised and are free to move through the whole structure. This sharing of Delocalised electrons results in a strong metallic bond. Metallic bond: Metallic bonds formed when the charge is spread over a large distance as compared to the size of a single item in a solids. Mostly in the periodic table, left elements form metallic bonds, for example zinc and copper. Because metals are solid, their atoms are tightly packed in a regular arrangement. They are so close to each other so valence electrons can be moved away from their atoms. A sea of free, Delocalised electron is formed surrounding a lattice of positively charged metal ions.These ions are held by strong attractive forces to mobile electrons,in this way, metallic bonds are formed.
