Inorganic refers to substances that do not contain carbon-hydrogen bonds, which are typically found in organic compounds. This category includes minerals, metals, and salts, such as sodium chloride (table salt) and quartz. Inorganic materials are essential in various fields, including chemistry, geology, and materials science. Inorganic compounds often have different properties compared to organic ones. For example, they can be good conductors of electricity and have high melting points. Common examples of inorganic substances include water, ammonia, and silica. These materials play crucial roles in everyday life, from construction to electronics.
