1.40 - 1.43 Ionic Bonding - properties

1.34 understand that ionic compounds have high melting and boiling points because of strong electrostatic forces between oppositely charged ions
1.35 understand the relationship between ionic charge and the melting point and boiling point of an ionic compound
1.36 describe an ionic crystal as a giant three-dimensional lattice structure held together by the attraction between oppositely charged ions
1.37 draw a diagram to represent the positions of the ions in a crystal of
sodium chloride

Video Exercise  : Watch the video and then answer the questions below
