• What is the strongest bond of the three you know? What is it made of ?

  Ionic bond, made of positively and negatively charged ions atrracting each other in an ionic lattice
• Arrange the types of bonds from strongest to weakest; ionic, vanderwaals, hydrogen, covalent

  Ionic bonds , covalent bond, hydrogen bond, vanderwaals bond
• The stonger the bond the higher the melting and boiling point
• A ionic lattice in a salt is a crystal structure made of ions held together by strong electrostatic forces of attraction.
• which binas table can you find melting point of salts in

  42A
• Why do salts have a higher melting and boiling point compared to molecular substances.

  Ionic bonds are stronger than the Vanderwaals bonds and hydrogen bonds in molecular substances
