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 it mean for metals to be malleable?

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

  Due to their regular structure
• What is the purpose of creating alloys?

  To make harder metals that resist bending
• What elements are typically combined to make steel?

  Iron and carbon
• What percentage of carbon is usually found in steel?

  One to two percent
• How do different sized atoms in alloys affect their properties?

  They disrupt the regular structure, increasing hardness
• What properties do we want in steel for its use in cars and planes?

  Strength and durability
• What is the main component of steel?

  Iron
• What is the purpose of the video discussed?

  To explain metallic bonding and alloys
• 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 do alloys differ from pure metals?

  • Alloys contain two or more different elements
  • They disrupt the regular atomic structure
  • Alloys are generally harder than pure metals
