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

A low boiling point and it conducts electricity when dissolved in water

A high melting point and it conducts electricity when molten or dissolved

A high boiling point and it conducts electricity when solid
