metallic bonding

• What is the structure of metals described as?

  A giant structure
• What happens to the electrons in the outer shell of metal atoms?

  They are delocalized and free to move
• What holds the atoms together in metallic bonding?

  Electrostatic attraction between ions and electrons
• How strong is metallic bonding?

  Very strong
• What types of substances are held together by metallic bonding?

  Metallic elements and alloys
• What do delocalized electrons in metallic bonds produce?

  All the properties of metals
• Why do metallic compounds have high melting and boiling points?

  Strong electrostatic forces require lots of energy
• What state are most metallic compounds at room temperature?

  Shiny solids
• Are metallic compounds soluble in water?

  No, they aren't soluble in water
• Why are metals generally more dense than non-metals?

  Metal ions are packed closely together
• What property allows metals to be hammered or rolled into sheets?

  They are malleable
• How do delocalized electrons contribute to conductivity?

  They carry electrical charge and thermal energy
• What basic physical properties do all metals share?

  Similar basic physical properties due to metallic bonding
• Why don't non-metals exhibit the same properties as metals?

  Non-metals lack metallic bonding
• What types of structures do non-metals form?

  A variety of different structures
• What are common characteristics of non-metals?

  Dull, brittle, lower boiling points
• How do non-metals generally behave chemically?

  They gain electrons to form full outer shells
• Where are non-metals typically located on the periodic table?

  Top and right-hand side
• How do metals behave chemically?

  They lose electrons to gain full outer shells
• Where are metals typically found on the periodic table?

  Bottom and left-hand side
• What are the key physical properties of metals?

  • High melting and boiling points
  • Shiny solids at room temperature
  • Generally dense
  • Malleable and ductile
  • Good conductors of electricity and heat
• What are the key physical properties of non-metals?

  • Dull appearance
  • Brittle
