What is the formula Trisilicon tetra nitride
The Correct Answer and Explanation is:
Correct Answer:
The chemical formula for trisilicon tetranitride is Si₃N₄.
Explanation:
Trisilicon tetranitride, commonly known as silicon nitride, is a compound consisting of silicon (Si) and nitrogen (N). The name follows traditional chemical nomenclature rules used in inorganic chemistry to describe the composition of covalent compounds.
The prefix “tri-“ in “trisilicon” indicates that there are three silicon atoms, and “tetra-“ in “tetranitride” indicates that there are four nitrogen atoms. The suffix “-nitride” is used to denote a binary compound containing nitrogen and another element, in this case, silicon.
When these atoms combine, the resulting compound is Si₃N₄. This formula represents one of the most stable and commonly occurring forms of silicon nitride.
Silicon nitride is a ceramic material known for its high strength, hardness, low thermal expansion, and excellent resistance to thermal shock. It does not oxidize easily and remains stable at very high temperatures, making it ideal for use in harsh environments. It is widely used in applications such as engine components, cutting tools, and bearings.
From a bonding perspective, silicon and nitrogen atoms are held together through strong covalent bonds. Each silicon atom typically forms four bonds, and each nitrogen atom usually forms three. In the crystalline solid structure of Si₃N₄, the atoms are arranged in a network that contributes to the material’s mechanical strength and thermal resistance.
In summary, the correct formula for trisilicon tetranitride is Si₃N₄, and it is a well-known material in both scientific and industrial contexts due to its impressive physical and chemical properties.
