Question

Maximum covalency shown by sulphur is:

• A. $2$
• B. $4$
• C. $6$
• D. none
  

Answer 1

Answer: (C)

$6$

$S=1s^{2}2s^{2}2P^{6}3s^{2}3p^4=6$

Sulpher is the member of $16$ group element so it's maximum covalency is $6$ also in it's excited state it has $6$ unpaired electron thus it has $6$ maximum covalency for example in $S{F}_6$ the maximum valency is $6$.
