    Cards (19)

    • 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
