Question

The formula of sulphur molecule is:
A) ${S_2}$
B) ${S_4}$
C) ${S_6}$
D) ${S_8}$

Answer 1

‌To solve this question, we must first understand the molecular properties of sulphur. Then we need to assess the properties that lead to the structure of the Sulphur molecule and then only we can have our correct answer.

Complete answer:
Before we move forward with the solution of this given question, let us first understand some basic concepts:
Sulphur $(S)$ , also spelled sulphur, a non metallic chemical element belonging to the oxygen group (Group $16$ of the periodic table), one of the most reactive of the elements. Pure sulfur is a tasteless, odourless, brittle solid that is pale yellow in colour, a poor conductor of electricity, and insoluble in water. It reacts with all metals except gold and platinum, forming sulfides; it also forms compounds with several nonmetallic elements. Millions of tons of sulfur are produced each year, mostly for the manufacture of sulfuric acid, which is widely used in industry.
The atomic number $(Z)$ of sulphur is sixteen and its electronic configuration is 2, 8, 6. The sulphur atom has six valence electrons. Sulphur is an octa-atomic molecule.
The chemical formula of sulphur molecules is ${S_8}$ . Each sulphur atom is linked to similar atoms on either side by single covalent bonds and thus, completes its octet. The molecule is in the form of a ring also represented by crown shape.
Therefore the correct option is option D..

Note: Sulphur is so widely used in industrial processes that its consumption often is regarded as a reliable indicator of industrial activity and the state of the national economy. Sulphur is used in the preparation of sulphuric uses which find many advantages in the industrial sector.
