Question

The correct set of decreasing order of electronegativity is:

• A. $Li,H,Na$
• B. $Na,H,Li$
• C. $Li,Na,H$
• D. $H,Li,Na$

Answer 1

The correct option is D $H,Li,Na$

The correct set of decreasing order of electronegativity is
$H>Li>Na$
In a group, electronegativity decreases from top to bottom due to increase in the atomic size.
