Question

odd one out giving reason of Sodium, Potassium, Sulphur, Silver

Answer 1

Heya !!!

This is Your answer.

Given :-
Sodium, Potassium, Sulpher, Silver.
Sodium :- A metal of high reactivity.
Potassium :- Most Reactive metal.
Sulpher :- A non metal with very high reactivity.
Silver :- A highly nonreactive metal.

We can see that three elements {Sodium, Potassium and Sulpher} are very reactive and they are stored in Kerosene oil.
Only Silver is very less reactive. 
Hence, Sliver is odd one out.

Hope It helps..

Answer 2

Silver is the odd one as it is less reactive and others are highly reactive
