Introduction Chemistry is the central science, a study of all that has mass and volume. An effort of this magnitude requires a clear language that communicates in a broad but consistent way.
At first appearance, chemistry may appear difficult because there are common words that take on new meaning in chemistry. For example, "salt" is a term widely used to describe table salt also known as sodium chloride. In chemistry, a salt is simply any compound composed of ions other than hydrogen ion, oxide ion, or hydroxide ion.
Sodium chloride is an example of a salt, as is potassium chloride, calcium carbonate and stannous fluoride. In chemistry, there is an effort to move away from using common names to identify the majority of compounds because this would require memorization of every single name.
Considering the vast number of ionic compounds over a million , a systematic method has been developed. As a student of chemistry you will learn how to translate a chemical formula into the systematic name and vice versa.
