Q

Properties of ionic substances?

A
  • brittle
  • can’t conduct electricity
  • soluble in water
  • height melting point
  • doesn’t conduct in a solid, but melted conducts

Q

Metallic bonding properties?

A
  1. High melting and boiling points
  2. Arranged In Regular pattern
  3. Give up outer shell electrons to share
  4. Positive ions are formed
  5. Free electrons moving between ions; it’s the thing that helps conduct everything and holds together
  6. 1 electron per atom
  7. Solid metal
  8. Sea of ‘ delocalised’ electrons
  9. Lattice of ions
  10. No intermolecular forces
