Question

Which of the following sets of elements are arranged in order increasing electronegativity.

• A. $S,Si,P$
• B. $Si,P,S$
• C. $S,P,Si$
• D. $Si,S,P$

Answer 1

Answer: (B)

$Si,P,S$

Electronegativity increases as we move left to right along period while as we move down the group electronegativity decreases.

since P ,S and Si belong to same group so correct of electronegativity i:

$Si<P<S$.
