Chemical interactions refer to the ways in which different substances, or chemicals, interact with one another. These interactions can lead to the formation of new substances through processes such as chemical reactions. Common types of chemical interactions include ionic bonds, covalent bonds, and hydrogen bonds, each characterized by different mechanisms of attraction between atoms or molecules. These interactions are essential in various fields, including biology, medicine, and materials science. For example, in biochemistry, chemical interactions are crucial for processes like enzyme activity and cellular signaling. Understanding these interactions helps scientists develop new drugs, create innovative materials, and explore the fundamental principles of matter.
