Linus Pauling's Development of an Electronegativity Scale

Return to the Bonding menu

The modern definition of electronegativity is due to Linus Pauling.

It is:

The power of an atom in a molecule to attract electrons to itself. (p. 88)

Although electronegativity, as a concept dates back to 1809, no one had been able to quantify it until Pauling in 1932.

He based his work on differences in bond energies. All page references are to "The Nature of the Chemical Bond" Third Edition (1960) by Linus Pauling.

Warning: the following discussion may get hard to follow, unless you have the underlying concepts.

I'm going to try and take it real slow, step-by-step.

In order to use electronegativity in your class, you don't have to understand how it came to be, so you can skip this stuff if you want. I feel safe in saying that no high school teacher is going to put this stuff on a test. What would be tested would be using the electronegativity scale, not how it came to be.

So why write thi
