Homework Help: chemistry

Posted by Andi on Tuesday, July 12, 2011 at 1:04pm.

Hi, my question:

The first five ionization energies of three different elements are:
1. 570 1800 2700 11600 15000
2. 740 1450 7730 10540 13600
3. 800 2400 3600 25020 32820

Which one of those elements is the most electronegative?

I know that electronegativity is a function of ionization energy and of affinity, so without any information about the affinity how can I tell which one of those elements is the most electronegative? (one of the possible answers for this question is that there isn't enough information for solving it).

Thanks in advance.
