Metallic Bonding

• What type of bonding occurs between metal atoms?

  Metallic bonding
• What characteristic properties arise from metallic bonding?

  Strength, high melting and boiling points
• 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 outer shell electrons in metallic bonding?

  They are shared among all atoms
• What do we call electrons that are free to move in metals?

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

  Electrostatic attraction
• Why are metals good conductors of electricity and heat?

  Delocalized electrons carry current and energy
• What does malleable mean in relation to metals?

  Can be bent or hammered into shapes
• Why can layers of metal atoms slide over one another?

  Due to their regular structure
• What is an alloy?

  A mixture of two or more different elements
• How do alloys differ from pure metals?

  Alloys have disrupted regular structures
• What is steel primarily made of?

  Iron
• What percentage of carbon is typically found in steel?

  One to two percent
• What additional elements can be found in steel for specific properties?

  Chromium, manganese, or vanadium
• Why are alloys used in cars and planes?

  They provide necessary strength and durability
• What are the key properties of metals due to metallic bonding?

  • High melting and boiling points
  • Good conductors of electricity and heat
  • Malleable and ductile
  • Strong due to electrostatic attraction
• How does the structure of alloys contribute to their hardness?

  • Alloys contain different sized atoms
  • Disrupts regular atomic structure
  • Prevents layers from sliding over each other
