Bonding

• Ionic bonding = bond formed between positively charged ion and negatively charged ions due to electrostatic forces
• Ionic bonding - between metal and non-metal
• Giant ionic lattic = regular structure, held together by ionic bonds

  
• Ionic Compound Properties:

  • high melting/boiling point -> held together by strong bonds
  • hard and brittle -> layers cant slide over each other
  • bad conductors of electricity -> no free delocalised electrons to carry and move charge (only when molten)
  • soluble in water -> as they have a dipole
