''Sulphur shows multiple valency.'' Explain this.

Explanation

a) Atomic number of sulphur is 16.
b) The distribution of electron is 2, 8, 6
c) Hence the valency should be '6'.
d) But it is easier to sulphur to gain 2 electrons than loosing 6 electrons to become octet.
Hence its valency would become 2.
e) So, sulphur shows multiple valency. i.e., '2' or '6'.
