SSC MTS 2022 PYQ — Question 46

The correct answer is option 3 i.e. 16

Atomic number of sulpur is 16 and its atomic mass is 32.

Properties of Sulphur-

1. Belongs to the Group-16 of the Periodic table.
2. Sulphur is a P-block Element.

3. Electron configuration of Sulphur  [Ne] 3s²3p⁴

4. Number of Valence Electron in Group-16 is 6.The valence electrons are the sum of the electrons in the outermost shell, that is two electrons and four electrons which gives a total of six valence electrons.

5. Valency of Sulphur - Sulphur requires two more electrons in order to complete its octet, hence its valency is 2.

Uses of Sulphur-

1. Sulfur is used in the vulcanisation of black rubber, as a fungicide and in black gunpowder.
2. It is used to make two of the essential amino acids needed to make proteins. It is also needed in some co-enzymes. The average human contains 140 grams and takes in about 1 gram a day, mainly in proteins.
3. used in the production of sulfuric acid, which is perhaps the most important chemical manufactured by western civilisations.
4. The most important of sulfuric acid’s many uses is in the manufacture of phosphoric acid, to make phosphates for fertilisers.
