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 ...

sodium + chlorine → sodium chloride magnesium + oxygen → magnesium oxide calcium + chlorine → calcium chloride lithium + oxygen → lithium oxide In all of these reactions, the metal atoms ...

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

This attraction pulls the atoms together and the electrons are shared by both atoms. The atoms bond because there is a strong enough attraction in both directions and room for the electrons in the ...
