perodic table

[Bethel Tesfamicael]

how to determine which element on the perodic table has a higher electronegativity when both are in the same period? Also are there exceptions to the electronegativity rule?

Hello! Electronegativity increases from left to right across groups and from down to up within a period. The more electronegative element would be the higher element in the period. The noble gases in group 18, can be excluded, but I dont recall if Lavelle discussed that in his lectures or not. Hope this helps!

When two elements are in the same period of the periodic table, electronegativity generally increases from left to right across the period. This means that the element closer to the right side of the period tends to have a higher electronegativity compared to the element closer to the left.
