What is the chemical formula for the compound formed between sodium and bromine?

When sodium (Na) and bromine (Br) react, they form sodium bromide. The chemical formula for this compound is NaBr. In this compound, each sodium atom donates one electron to a bromine atom, resulting in an ionic bond that connects the positively charged sodium ions and negatively charged bromide ions. It's a classic example of how metals and nonmetals combine to form ionic compounds! Sodium bromide is not just a textbook example; it has practical applications too! It’s used in the pharmaceutical industry, particularly for its sedative properties, and in photography for its silver bromide content. It also plays a role in saltwater aquariums to help maintain necessary salinity levels, showcasing the fascinating interplay of chemistry in various fields!
