PPT Lewis Diagrams for Polyatomic Ions PowerPoint Presentation ID


Na and Br are two of the most commonly used chemical elements in various industries. Sodium (Na) is a highly reactive alkali metal, while Bromine (Br) is a non-metal halogen. They have different properties and applications, but when combined, they form a compound that is widely used in many fields. In this article, we will explore the chemical formula of Na and Br, their properties, and applications.

The Chemical Formula of Na and Br

The chemical symbol for sodium is Na, which comes from the Latin word ‘natrium.’ Sodium has an atomic number of 11 and is classified as an alkali metal. It has a single electron in its outer shell, which makes it highly reactive. Bromine, on the other hand, has a chemical symbol of Br and an atomic number of 35. It is classified as a non-metal halogen and has seven electrons in its outer shell.

When Na and Br are combined, they form a compound called sodium bromide (NaBr). The chemical formula for sodium bromide is NaBr, which means it contains one sodium atom and one bromine atom. NaBr is a white crystalline powder that is highly soluble in water and has a salty taste.

The Properties of NaBr

NaBr has several unique properties that make it useful in different industries. It has a high melting point of 747°C and a boiling point of 1390°C. It is also highly soluble in water, with a solubility of 90g/100mL. NaBr is a stable compound that does not react with most acids or bases.

NaBr is also an excellent conductor of electricity, which makes it useful in the production of batteries and other electronic devices. It is also used as a photographic chemical and in the manufacturing of pharmaceuticals, dyes, and flame retardants.

The Applications of NaBr

Due to its unique properties, NaBr has various applications in different industries. In the pharmaceutical industry, it is used to manufacture sedatives, anticonvulsants, and other drugs. It is also used in the production of photographic films, where it acts as a salt to control the sensitivity of the film.

NaBr is also used as a flame retardant in the textile industry. It is added to fabrics to make them less flammable and reduce the risk of fire. In the oil and gas industry, NaBr is used as a completion fluid that prevents the collapse of underground formations during drilling operations.

The Environmental Impact of NaBr

NaBr is generally considered safe for human and environmental health. However, like any chemical compound, it can be harmful if not handled properly. It can cause skin and eye irritation, and prolonged exposure can lead to respiratory problems.

NaBr can also have an impact on the environment if not disposed of properly. It can contaminate water sources and harm aquatic life. Therefore, it is essential to follow proper disposal methods and regulations to prevent any negative effects on the environment.


NaBr is a versatile compound that has various applications in different industries. Its unique properties make it useful in the production of drugs, photographic films, flame retardants, and completion fluids. However, it is essential to handle NaBr with care and dispose of it correctly to prevent any negative effects on human health and the environment.

Understanding the chemical formula and properties of Na and Br can help us appreciate their importance and applications in our daily lives. As we continue to explore and discover new compounds, it is crucial to consider their impact on human health and the environment to ensure a sustainable future for all.
