Question

The correct order of electronegativity on Pauling scale is:

• A. $F>CI>O>S$
• B. $Li>Na>K>Rb>Cs$
• C. $Be<B<N<C$
• D. Both (A) and (B)

Answer 1

The correct option is B $Li>Na>K>Rb>Cs$

Electronegativity is a measure of an atom's ability to attract shared electrons to itself.

Electronegativity decreases down the group and increases as we move from left to right across a period in a periodic table.
Option (a) is wrong because electronegativity of oxygen is greater than chlorine.
Option (b) is right because electronegativity decreases down the group.
Option (c) is wrong because electronegativity of nitrogen is greater than carbon.
