Question

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.

Answer 1

electronegativity=high ionization energy

element 3
