they have strong
bonds in three
dimensions
- Properties of ionic substances
include high melting and boiling
points, being soluble in water and
conducting electricity when
aqueous or molten
- Ionic substances can
conduct electricity
when molten
because high
temperatures break
the strong bonds
between the ions
and so the ions are
free to move in the
liquid
