Compounds are substances made up of two or more elements that are chemically bonded together. These elements can be from the same group or different groups on the periodic table. Compounds have unique properties that are different from their constituent elements, and they can be formed through various chemical reactions. Compounds play a crucial role in many scientific fields, such as chemistry, biology, and materials science, and are essential for understanding the complex interactions and processes that occur in these disciplines. Research on compounds focuses on their properties, synthesis, structure, and applications in different industries and technologies. This research area is constantly evolving as scientists continue to discover new compounds and explore their potential uses in various fields.
