Question

What is the correct order of electronegativity?

• A. $M^{1-}$ < $M^{2-}$ < $M^{3-}$ < $M^{4-}$
• B. $M^{1-}$ > $M^{2-}$ > $M^{3-}$ > $M^{4-}$
• C. $M^{1-}$ < $M^{2-}$ < $M^{3-}$ < $M^{4-}$
• D. $M^{4-}$ < $M^{2-}$ < $M^{3-}$ < $M^{1-}$

Answer 1

The correct option is B

$M^{1-}$ > $M^{2-}$ > $M^{3-}$ > $M^{4-}$

Electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself. It mainly depends on two factors:

• Atomic Size
• Nuclear Charge

Lesser the negative charge more would be its tendency to attract the shared pair of electrons towards itself.
