This field of chemistry focuses on the array of molecules that are formed by different processes. You will find that this mainly deals with the structure and function of different ions. Especially important is the study of how they arrange themselves in space to form solids. It is extremely applicable to industrial areas of the world. It provides the basis for the manufacture of ammonia, hydrogen peroxide, and sodium hydroxide, among a variety of other useful chemicals.
Inorganic chemistry can also be uniquely broad in scope. Certain chemists may focus their efforts on the study of different materials (IE ceramics). Others may look for ways to improve synthesis of different important base chemicals like ammonia. Still others may spend their lives developing technology based on the element silicon. This unique breadth means that you are unlikely to find two inorganic chemists who are exactly alike.
Inorganic chemistry education at the basic level will put significant emphasis on expanding the concepts studied in general chemistry relating to crystal structure as well as the analysis and characterization of transition metal compounds.
