salt water
Sodium chloride (chemical formula NaCl), known as table salt, rock salt, sea salt and the mineral halite, is an ionic compound consisting of cube-shaped crystals composed of the elements sodium and chlorine. This salt has been of importance since ancient times and has a large and diverse range of uses. It can be prepared chemically and is obtained by mining and evaporating water from seawater and brines.
Sodium chloride is colorless in its pure form. It is somewhat hygroscopic, or absorbs water from the atmosphere. The salt easily dissolves in water. Its dissolution in water is endothermic, which means it takes some heat energy away from the water. Sodium chloride melts at 1,474°F (801°C), and it conducts electricity when dissolved or in the molten state.

An ionic compound such as sodium chloride is held together by an ionic bond. This type of bond is formed when oppositely charged ions attract. This attraction is similar to that of two opposite poles of a magnet. An ion or charged atom is formed when the atom gains or loses one or more electrons. It is called a cation if a positive charge exists and an anion if a negative charge exists. …
Since ancient times, the salt sodium chloride has been of importance. It has been used in numerous ways including the flavoring and preserving of food and even as a form of money. This salt improves the flavor of food items such as breads and cheeses, and it is an important preservative in meat, dairy products, margarine and other items, because it retards the growth of microorganisms.

I have a question regarding a science assignment on a neutral ionic compound.
I have chose Sodium Chloride and I was wondering, could anyone tell me what I should put for a description of the properties of both sodium and choloride when they are as a single element.
ANY help from ANYONE would be much appreciated ~
