What charge will group 1 elements form?
What charge will the halogens form?
What is ionic bonding?
Electrostatic attraction between ion formed by the transfer of electrons
Ionic compounds have what type of boiling and melting points? Why?
High, because they are lattice structure so ionic bonds would have to be broken
When melted or dissolved in water ionic compounds conduct electricity, why?
Ions are free to move
