Electronegativity.

Electronegativity is found by experiment and interpreted as shown on:

There is, as far as we are aware; no theoretical mathematical formula. Fortunately there are two sequences in the Table of Elements on:

http://69.5.17.59/et1.pdf

That is sufficiently similar in structure to produce a theoretical mathematical formula as shown in the table. Col. (d) shows that the values produced by the equation:

r/(1/e)

e = electronegativity

produces the same values for both sequences of elements; demonstrating that electronegativity is inversely proportional to the atomic radius.

The table can be found on:

This is a fairly straightforward relation, since the tighter an atom holds its own electrons (i.e. the smaller it's radius), the tighter it will grab on to some other atom's electrons (it's electronegativity).

I think your equation could be simplified to:

r*e = C

I have no idea what C would be however.

Embarrassingly I have to admit to an error in copying data from column to column in Excel.

no worries. It was an interesting to chew on though.
