Inorganic Chemistry: Core Concepts

• Chemistry is the study of matter and its properties as well as how matter changes
• Inorganic chemistry is the study of the properties and behavior of inorganic compounds
• Inorganic compounds include minerals, metals and organometallic compounds
• It is a broad field that encompasses all chemical compounds except for the myriad organic compounds (carbon-based compounds), which are the subjects of organic chemistry
