Which element in period 4 has the highest electronegativity?

Chemistry
1 answer:
sashaice [31]3 years ago
8 0
It will be K-potassium because when you go down a group the electronegativty gets bigger while when you go across the period they get smaller because of the valence electrons. Group 8 has the lowest electronegativty because they have a full outer shell. From left to right on the periodic table it decreases but from top to bottom it increases.
