Is Lithium Bromide Ionic or Covalent?

All About Lithium Bromide

One of the most common questions is "is lithium bromide ionic or covalent?" The answer is simple and straightforward. Lithium bromide is an ionic compound consisting of lithium and Bromine. In fact, lithium is an alkali metal. It has a total of 3 electrons. It is important to remember that lithium only has one electron in its valence shell. On the other hand, bromine is not a metal. Bromine has a total of 35 electrons in only one atom. Compared to lithium which only has one electron in its valence shell, bromine has 7 electrons in its valence shell. The common quality between lithium and bromine is they both become stable by attaining an electronic configuration most similar to noble gas. The official name for the new compound created via this process is lithium bromide or LiBr.

One of the most important qualities of LiBr is its hygroscopic properties. Hygroscopic means a substance is able to attract water molecules through adsorption or absorption. This process can be completed from the surrounding environment. It typically only occurs at room temperature or "normal" temperature. In fact, you may have noticed lithium bromide is commonly used as a desiccant. It does an incredible job at absorbing moisture from the surrounding environment. Therefore, this ionic compound has many uses in multiple industries.

Why Is Lithium Bromide Ionic or Covalent? Let's Take a Closer Look

Let's take a look at the chemical and physical properties of lithium bromide.

• Lithium bromide is categorized as a white hygroscopic solid.
• The density of lithium bromide is 3.4 grams.
• Lithium bromide is fully soluble in water. In fact, as the temperature of the water increases, the solubility of the ionic compound increases as well.
• Water is not the only liquid lithium bromide is soluble in. It is also soluble in ethanol, methanol, acetone and ether, among other liquid substances.
• When it comes to partial solubility, lithium bromide is partially soluble in pyridine.
• Lithium bromide is not a flammable ionic compound.
• It has the ability to dissolve multiple organic compounds. A prime example of this could be the organic compound cellulose.
• The anhydrous form of lithium bromide produces cubic crystals.
• This ionic compound does react with other substances such as chlorine. It reacts with the chlorine molecules and forms two new substances known as bromine gas and lithium chloride salt.
• Lithium bromide is also commonly known to react with silver nitrate. Two new substances are formed during this reaction which includes silver bromide and lithium nitrate.
• The melting point of lithium bromide is 552 �C.
• Lithium bromide is formed via the transfer of electrons. As soon as lithium donates one electron, it gets a positive charge. This positive charge is known as Li+. Once bromine accepts this electron from lithium, it gets a negative charge. This negative charge is known as Br. It is important to remember the crystal structure of lithium bromide is cubic.

Let's take a look at the many uses of lithium bromide today. Is lithium bromide ionic or covalent?
