ChemistryHow are electronegativity values for elements determined?

Postby Jennifer Guzman 4C » Sun Nov 11, 2018 11:20 pm

I understand that electronegativity is the tendency for elements to attract electrons, but I was wondering how the specific values for each element is calculated?

I'm not sure how the values for electronegativity are calculated, but they are based on the element's electron affinity and ionization energy. I believe we don't need to know how to calculate it, we just need to know the definition and how it relates to covalent bonds and other topics.

I believe Dr. Lavelle mentioned that they are experimentally measured.

The electronegativity values are experimentally calculated. There is a chart in the book that lists electronegativity values, so you can just use that. As a general rule, elements further apart on the periodic table will have a higher difference in electronegativity.
