How is electronegativity calculated?

Dr. Lavelle said we will be given the values for electronegativity when we calculate differences. However, he did state in lecture that electronegativity is generally calculated by adding the ionization energy and electron affinity and dividing that sum by some constant. Don't worry about calculating electronegativities for now, though.

All we need to know is the trend of electronegativity. You should generally be able to tell which element is more electronegative when comparing between elements. However, you won't need to actually calculate the exact values. If there's a situation where the exact values are important a chart will be provided.

When we calculate electronegativity, values will be given to us either in the form of a periodic table with those values listed or something similar.

To calculate electronegativity, you simply take the difference between the two elements. And using these values, you can see if the compound is polar or nonpolar, as well as having possibly ionic characters or covalent.
