Metallic

• Metallic bonding


  The type of bonding you get between metal atoms
• Metallic bonding


  • Gives rise to the characteristic properties of metals
• Metals bond to non-metals through ionic bonding
• Non-metals bond to other non-metals through covalent bonding
• Metallic bonding

  Metals bond to other metals
• Metallic bonding

  1. Atoms give up their outer shell electrons

  2. Electrons become delocalized

  3. Strong electrostatic attraction between positive ions and negative electrons

  4. Holds everything together in a regular structure
• Metallic bonding

  • Gives the overall metal strength
  • Means most metallic structures have high melting and boiling points
  • Metals are good conductors of electricity and heat
  • Metals are malleable
• Alloy

  Contains two or more different elements, either by mixing together two different metals or a metal and a non-metal
• Alloys


  • Combination of different sized atoms disrupts the metal's regular structure
  • Layers can no longer slide over one another
  • Alloy is much harder than pure metal
• Steel

  • Made up mostly of iron
  • Also contains 1-2% carbon
  • Sometimes contains chromium, manganese or vanadium
