Calcium becomes a +2 ion and each chlorine becomes a -1 ion. The +2 calcium ion and the two -1 chloride ions attract each other and form an ionic bond and the compound calcium chloride. One calcium ...

neutrons, electrons, and energy levels in atoms and their location in the periodic table. Students will also explore covalent and ionic bonding.

The lattice arrangement continues in three dimensions. This is why solid ionic compounds form crystals with regular shapes.
