Which properties are all characteristics of ionic compounds?

• solids with high melting and boiling points

• soft solids which are highly malleable

• when solid, the ions are held in place so the compounds cannot conduct electricity

• conduct electricity when dissolved or molten

Why do ionic compounds have high melting and boiling points?

• Their ions are free to move.

• Their ions are held in fixed positions.

• They have many strong bonds which require a large amount of heat energy to overcome these strong bonds.

• They have weak bonds which require a little amount of heat energy to overcome these weak bonds.
