WebThat is why electronegativity goes down as you go down a Group of the periodic table in the s and p blocks (the d block is different). In the d-block, you have many competing factors such as then need to have a full s and p, to energetic nuances due to the d subshell being partially full, and all these affect the electronegativity. WebEssentially, our task is to compare the electronegativities of these elements and find the diatomic molecule that has the atom with the highest electronegativity and the lowest electronegativity. We can solve this problem two different ways.
