The element in period 4 of the Periodic Table with the highest electronegativity is krypton (2.96). The period 4 element with the lowest electronegativity is potassium (0.82).
The element in period 4 that has the greatest electronegativity is Fluorine. Electronegativity will increase from left to right in the period.
Carbon.
V-Vanadium
Electronegativity increases to the right of the table and up the table. So the most electronegative elements are at the top right, the least electronegative are at the bottom left. Fluorine is generally said to be the most electronegative element. This is not strictly true since both Helium and Neon are obviously more electronegative - however it is no good to say so since they are both massively inert. Whereas the electronegativity of Fluorine is important as it helps define its chemistry. Oxygen, nitrogen and chlorine all have high electronegativity but it tends to become a bit of a non-issue beyond that.
Scandium is a period 4 element.
There are 4 electronic shells in period 4 while there are 5 shells in period 5.Elements of period 4 are smaller in size as compared to elements of period 5.Example of period 4 element is potassium and period 5 element is tin.
There is no such element on the Periodic Table
Fluorine has the highest electronegativity of any element. Its electronegativity is 4. Oxygen has the second highest electronegativity of any element, with an electronegaitivity of 3.5, and chlorine has an electronegativity of 3.16 on the Pauling scale. Note that there is more than one scale for measuring electronegativity. But no matter which scale you use, Fluorine is more electronegative than oxygen, which is more electronegative than chlorine.

All acids consist of some non-metallic element or radical that is combined with hydrogen. There is a quantity called electronegativity which measures the degree to which a given atom or radical attracts electrons. The higher the electronegativity that any given atom or radical has, the stronger the acid it will form when it combines with hydrogen. The highest known electronegativity is 4, which is the electronegativity of fluorine. Therefore, hydrofluoric acid is the stongest acid.
Br (Bromine) is a period 4 element in the same group as F.
There is no element with 28 protons in group 4. I think you are getting confused with group 4 and PERIOD 4. In period 4, the element with 28 protons is Nickel.
