__Metals__ like sodium and calcium form positive ions, or ___cations___.
___Nonmetals____ like chlorine and oxygen form negative ions, or __anions___.
Ionic bonds form by the __transfer__ of ___electrons___.
One positive ion attracts several __negative__ ions. One negative ion attracts several __positive__ ions. These many attractions form strong __networks__ like NaCl (table salt). (Remember we said that network structures have very high melting points.)
Ionic Compounds conduct __Electricity___ when dissolved in water.
Electricity is just moving charges, and as solids, ionic compounds are __strong__ and can’t __move__, which means their solid form cannot conduct electricity. (Remember the high melting points-It takes a lot to melt these network structures because it takes a lot of energy to break those strong ionic bonds!!)
Ions will __split__ apart in water and can _move_ freely, meaning an electric charge can also move through, or be “__Conducted__”.
