Sodium Chloride is an alkali halide with an fcc crystal structure. The basis is two ions, a sodium cation and a chlorine anion. The crystal lattice parameter is 0.563 nm. The diagram shows both a unit ...

A pure substance made from more than one type of element chemically bonded together. Elements bond in fixed ratios and so can be represented by a chemical formula. For example, sodium chloride has ...

Table salt – as well as the other types of salt – consists of a compound of sodium and chloride ions to make sodium chloride (NaCl if you like chemistry). The sodium in salt is where the ...

A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic compound sodium chloride is formed. A sodium and chlorine atom are near ...
