Question

The atomic number of elements is \[16\]. The number of valence electrons in the elements is:
A. \[4\]
B. \[5\]
C. \[6\]
D. \[7\]

Answer 1

Hint: The atomic number of the element is given and the number of valence electrons is to be determined out of the given options. It is known to us that; the number of electrons which are present in the outer shell of an atom is called valence shell electrons.

Complete step by step answer:
As we know that, the atomic number of elements is 16. The electronic configuration and the name of the element can be determined as the atomic number is fix for the particular element. To determine the number of valence electrons, the configuration should be known.
Sulfur is a chemical element having the symbol as “S”. It is placed in the periodic table and atomic number is \[16\], with electronic configuration . There are six electrons in ${\rm{3s}}$ and ${\rm{3p}}$ orbitals. Therefore, we can say that there are six valence electrons present in sulfur.
Oxides of Sulphur cause air pollution and it is very harmful for destroying the natural environment. Sulphur easily gets combined with oxygen to form stable oxides which have various uses in the ore extraction industry. Sulphur is used as a vulcanizer, it is used in making fungicides and to make firecrackers and gunpowder.

Hence, the correct option is (C).

Note:
Sulphur is the only atom in the \[{S_8}\]. It has crown shape structure, which no other molecule has.
