Sodium chloride has ionic bonds and form big lattices.
The Reaction between Sodium and Chlorine. Chlorine has 7 electrons in its outer shell. It is in group 7 of the periodic table. When an atom of chlorine reacts it will gain one electron from sodium. The outer shell of chlorine will then have 8 electrons and be full. The chloride ion will have an extra electron and therefore an extra negative charge (shown as a - sign). What is an Ionic Bond? The electrostatic force of attraction between the oppositely charged ions is called an ionic bond. The electrons are shown as dots and crosses to show how they have moved during the reaction. In reality all electrons are identical. The balanced chemical equation for the above reaction is. sodium + chlorine sodium chloride.
