👉 In chemistry, an ionic compound is a substance that contains atoms or ions bonded together by electric charge. Ionic compounds are characterized by their ability to form positively charged ions and negatively charged electrons. This characteristic makes them useful for various practical applications such as batteries, electrolysis, and in the development of new materials. For example, lithium (Li) and sodium (Na) ions can be combined through a process called ionic reaction, which is described below: \[ Li + Na \rightarrow Li^
