How we get valency 2 in sulphur?
Asked by Jaiwanthsiva | 15 Apr, 2020, 01:51: PM
Expert Answer
Atomic number of Sulphur is 16
 
Electronic configuration : 2,8,6
 
So, there are 6 valence elctrons in outermost orbit.
To obtain a stable electronic configuration of octet state, it is easier to gain 2 electrons than to lose 6 electrons.
 
Tharfore sulphur will acquire octet state by accepting 2 electrons and hence valency of sulphur is 2.
