Question

The elements Li, B, C, Be and N have
the electronegativities 1.0, 2.0, 1.5 and
3.0, respectively on the Pauling scale.​

Answer 1

Hello Dear,

Not sure what you want to know. But I'll explain in brief about Pauling scale of electronegativity so you get your answers.

◆ Pauling scale of electronegativity -

• Pauling scale measures electronegativity of elements in periodic table.
• According to Pauling, electronegativity is the power of an atom in a molecule to attract electrons to itself.
• Pauling calculated electronegativity with this formula -

|χA - χB| = 0.208 ΔE1/2 [eV]

• Electronegativity difference between two atoms helps us to know ionic character of the bond.

Thanks dear...
