ionic compounds Flashcards
what is the structure of ionic compounds called?
giant ionic lattice
in an ionic compound, what is every positive ion surrounded by?
every positive ion is surrounded by a negative ion
in an ionic compound, what is every negative ion surrounded by?
every negative ion is surrounded by a positive ion
there are strong forces of attraction between negative and positive ions, what are these forces called?
these forces are called electrostatic forces of attraction
ionic compounds have ____ melting and boiling points?
ionic compounds have high melting and boiling points
why do ionic compounds have high melting and boiling points?
because they have strong electrostatic forces which require lots of energy to break
can ionic compounds conduct electricity?
not when they are solids, only when they have been melted or dissolved in water
why cant ionic compounds conduct electricity when they are solid?
because they are locked in place by electrostatic forces of attraction
why can ionic compounds conduct electricity when melted or dissolved?
because the ions are now free to move about and carry electric charge
