Final Exam Review #9

Explain which group in the periodic table has the highest electronegativity values? Why do noble gases tend to have electro negativities of zero?

Halogens have the highest electronegativity values because as you move across to the right of the periodic table, the elements want to attract more electrons and protons to make the configuration more stable.  Halogens have the largest, greatest desire to attract one more electron to become a noble gas stable configuration.

Green squares are the halogens
Noble gases tend to have electro negativities of zero because they have a stable configuration and do not want to attract electrons when their atoms are in a stable compound.
