Question
Chemistry Question on Classification of elements & periodicity in properties
Select the correct order of electronegativity of the elements: B, C, At, S
A
B > C > S > At
B
S > C > B > At
C
C > B > S > At
D
S > C > At > B
Answer
S > C > At > B
Explanation
Solution
The correct option is (D): S > C > At > B
The electronegativity of B(2), C(2.5), At(2.2) and S(2.58).
Therefore, the order will be S > C > At > B
