Write The Chemical Formula For Barium Nitride

What is the Chemical Formula for Barium Nitride?

Barium nitride is an inorganic compound formed from the ionic bonding between barium (Ba) and nitride (N³⁻) ions. Understanding its chemical formula requires knowledge of the charges of these ions. This article will explain how to derive the formula and delve into some of its properties. This is a great example of a simple inorganic compound, useful for understanding basic chemical principles.

Barium is an alkaline earth metal in group 2 of the periodic table, meaning it readily loses two electrons to achieve a stable electron configuration. This results in a +2 charge, forming the Ba²⁺ ion. Nitrogen, on the other hand, is a nonmetal in group 15 and gains three electrons to form the nitride ion, N³⁻, achieving a stable octet.

To create a neutral compound, the positive and negative charges must balance. This is achieved through a process of finding the least common multiple (LCM) of the charges. The LCM of 2 and 3 is 6. Therefore, we need three barium ions (3 x +2 = +6) to balance the charge of two nitride ions (2 x -3 = -6).

Therefore, the chemical formula for barium nitride is Ba₃N₂. This formula indicates that there are three barium atoms for every two nitrogen atoms in the compound.

Properties of Barium Nitride

Barium nitride is a crystalline solid with a dark grey or brownish-black color. It is relatively reactive and readily reacts with water and moisture in the air, producing ammonia gas (NH₃) and barium hydroxide. This reaction is exothermic, meaning it releases heat. This sensitivity to moisture is a key characteristic to remember when handling this compound.

Key characteristics include:

• High melting point: Due to strong ionic bonding.
• Insoluble in water (but reacts vigorously): The reaction with water prevents simple solubility.
• Reacts with acids: Forms barium salts and ammonia.
• Forms ammonia upon hydrolysis: This is a distinctive reaction used for its identification.

Applications of Barium Nitride

While not as widely used as some other barium compounds, barium nitride finds niche applications in various fields, including:

• Synthesis of other nitrogen-containing compounds: It serves as a starting material for the preparation of other materials.
• Material Science Research: Its unique properties are explored for potential applications in various materials.

Understanding the chemical formula, Ba₃N₂, and the properties of barium nitride is crucial for safe handling and for potential applications in various scientific and industrial fields. Remember to always prioritize safety when dealing with reactive chemical compounds.
