Ionic bonds are characterized as
- bonds between metals non-metals
- bonds between cations anions
- bonds involving a transfer of e- (from a metal
to a nonmetal)
3
Ionic compounds form crystalline lattice
structures which are very strong.
High Melting Point
Ex. Melting point for NaCl is 800C

Starting Total Charge 0
Anions have larger atomic radii
Remember!!!
5
When ionic compounds dissolve into solution,
their and ions separate (electrolyte).
6
Good electrolytes, like many ionic compounds are
good conductors of electricity.
Electrolysis

How do ionic compounds with subscripts form?
Ex. How does MgCl2 form?
