what is ionic bonding?
a strong electrostatic attraction between oppositely charged ions
why do compounds with giant ionic lattices have high melting and boiling points?
Ionic compounds have high melting and boiling points because they have a giant structure with strong electrostatic forces between oppositely charged ions that require a lot of energy to break.
do ionic compounds conduct electricity?
not when solid, but they do if molten or in solution
