Although the details of the structure of monoclinic sulphur are not well known it probably consists of
- $S_8$ chains
- $S_2$ molecule
- $S_8$rings
- $S_4$ rings
The Correct Option is C
Approach Solution - 1
Approach Solution -2
The structure of monoclinic sulfur is not perfectly understood, but it's widely accepted that monoclinic sulfur primarily consists of S8 rings.
The elemental form of sulfur (S) usually exists as S8 molecules, where eight sulfur atoms are arranged in a ring. These S8 rings can further form various structures. In monoclinic sulfur, these rings are thought to arrange themselves in such a way that they form long chains. This arrangement allows monoclinic sulfur to exhibit unique physical properties.
So, the correct option is (C): S8 rings

Concepts Used:
Group 16 Elements
The group 16 elements (oxygen group elements) of the periodic classification are also known as chalcogens because most of the copper ores have copper in the form of oxides and sulphides. The word chalcogen means “ore formation” which is derived from the Greek word “Chalcos” (Ore) and “gen” (formation).
There are 5 elements that come under Group 16 of the Modern Periodic Table namely:
- Oxygen (O)
- Sulphur (S)
- Selenium (Se)
- Tellurium (Te)
- Polonium (PO)
Electronic Configuration:
The general electronic configuration of the chalcogens can be written as ‘ns2np4’, where ‘n’ denotes the value of the principal quantum number corresponding to the valence shell of the element.
The electron configuration of the synthetic element livermorium (believed to be a chalcogen) is predicted to be [Rn]5f146d107s27p4.
Metallic Nature of the Group 16 Elements:
- Oxygen and sulfur are classified as non-metals.
- Selenium and tellurium are classified as metalloids.
- Under standard conditions, polonium exhibits metallic characteristics. However, it is important to note that polonium is a radioactive element.
