Metallic bonding

• What type of bonding occurs between metal atoms?

  Metallic bonding
• What are the characteristic properties of metals attributed to metallic bonding?

  Strength, high melting and boiling points, good conductivity, and malleability
• How do metals bond to non-metals?

  Through ionic bonding
• How do non-metals bond to other non-metals?

  Through covalent bonding
• What happens to the outer shell electrons when metal atoms bond together?

  They give up their outer shell electrons and share them with other atoms
• What are delocalized electrons?


  Electrons that are free to move about in a metallic structure
• What type of attraction holds the metallic structure together?

  Strong electrostatic attraction between positive ions and delocalized electrons
• Why do most metallic structures have high melting and boiling points?

  Due to the strong forces of attraction in the metallic bonding
• Why are metals good conductors of electricity and heat?

  Because delocalized electrons can carry electrical current and thermal energy
• What does it mean for metals to be malleable?

  They can be easily bent or hammered into shapes
• How does the regular structure of metals affect their malleability?

  It allows different layers to slide over one another
• What is an alloy?


  A mixture of two or more different elements, usually including a metal
• How are alloys typically made?

  By mixing together two different metals or a metal and a non-metal
• Why do different sized atoms in alloys make them harder?

  They disrupt the regular structure, preventing layers from sliding over one another
• What is steel primarily made of?

  Iron
• What elements can be added to steel to enhance its properties?

  Carbon, chromium, manganese, or vanadium
• Why is steel used in cars and planes?

  Because of its strength
• What are the key properties of metals due to metallic bonding?

  • Strength
  • High melting and boiling points
  • Good conductors of electricity and heat
  • Malleability
• How do alloys differ from pure metals?

  • Alloys contain two or more different elements
  • Alloys have disrupted regular structures
  • Alloys are generally harder than pure metals
