Metallic Bonding

• How do non-metals bond to other non-metals?

  Through covalent bonding
• What do we call the electrons that are free to move in metallic bonding?

  Delocalized electrons
• What type of attraction holds the structure of metals together?

  Electrostatic attraction
• What percentage of carbon is typically found in steel?

  One to two percent
• In what applications is steel commonly used due to its strength?

  In cars and planes
• What type of bonding occurs between metal atoms?

  Metallic bonding
• What happens to outer shell electrons in metallic bonding?

  They are given up and shared among all atoms
• How are alloys typically made?

  By mixing two different metals or a metal and a non-metal
• What additional elements can be found in steel to enhance its properties?

  Chromium, manganese, or vanadium
• What are the key properties of metals due to metallic bonding?

  • High melting and boiling points
  • Good conductors of electricity and heat
  • Malleability (can be bent or hammered)
• Why are metals good conductors of electricity and heat?

  Because delocalized electrons can carry current and thermal energy
• What is steel primarily made of?

  Iron
• What type of bonding occurs between metal atoms?

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

  Metallic bonding
• What are the key properties of metals due to metallic bonding?

  • High melting and boiling points
  • Good conductors of electricity and heat
  • Malleability (can be bent or hammered)
• How do alloys differ from pure metals in terms of structure and properties?

  • Alloys contain two or more different elements
  • Different sized atoms disrupt regular structure
  • Alloys are generally harder than pure metals
• Why are metals good conductors of electricity and heat?

  Because delocalized electrons can carry current and thermal energy
• Why do most metallic structures have high melting and boiling points?

  Due to strong metallic bonding
• How do non-metals bond to other non-metals?

  Through covalent bonding
• Why do most metallic structures have high melting and boiling points?

  Due to strong metallic bonding
