A positive ion will be attracted to any negative ion.

A sodium ion is only bonded to the chloride ion it donated its electron to.

A sodium atom can only form one ionic bond, because it only has one electron in its outer shell to donate.

The reason a bond is formed between chloride ions and sodium ions is because an electron has been transferred

between them

In the diagram a chloride ion is attracted to one sodium ion by a bond and is attracted to other sodium ions just by forces.

In the diagram each molecule of sodium chloride contains one sodium ion and one chloride ion.

An ionic bond is the attraction between a positive ion and a negative ion.

A positive ion can be bonded to any neighbouring negative ion, if it is close enough

It is not possible to know where the ionic bonds are, unless you know which chloride ions accepted electrons from which sodium ions

A chloride ion is only bonded to the sodium ion it accepted an electron from.
