Metallic Bonding

• Metallic bonding involves the bonding of 2 metals
• Solid metals consist of a giant structure of atoms that are arranged in a regular pattern
• Atoms which are together in a metal, they give up these outer shell electrons and share them with all the other atoms which leads to them becoming positive ions as they lost negative electrons
• Those negative electrons lost would be allowed to freely move about they would be known as delocalized electrons
• Metallic Bonding:

  There would then be loads of electrostatic attraction between the positively charged ions and negatively charged ions and these forces are what hold everything together in a regular structure
• Properties of Metallic Bonding:

  • High Melting / Boiling points
  • Can conduct electricity : as delocalized electrons can carry electrical current and thermal energy thoughout the structure
  • Malleable : Bent or hammered into shapes
• Alloys : A mixture of two or more metals, usually with a lower melting point than the pure metals and harder to bend

  • Generally used with different sized atoms which can help to disrupt the metals regular structure
