Detailed Solution

Concept- The element's atomic number is provided, and among the possibilities supplied, the number of valence electrons must be chosen. We are aware that the quantity of electrons in an atom's outer shell is known as the valence shell electrons.
The electrons present in the outermost shell of an atom are known as valence electrons.
The atomic number of elements is 16, so the electronic configuration is 2, 8 and 6. Therefore, the valence electrons in the element is 6.Sulfur oxides are very harmful for destroying the natural environment and for causing air pollution. Sulfur and oxygen combine readily to form stable oxides, which have a variety of applications in the ore extraction sector. Sulfur is a vulcanizer, an ingredient in fungicides, and a component of gunpowder and firecrackers.
Hence, the correct answer is option (3).
