The elements whose atoms have the tendency to gain electrons are called electronegative elements and this tendency is known as electronegativity. Electronegativity of any element depends on its size. As the size decreases , the tendency to gain electron increases and in turn increases the electronegativity.
For group-17 elements (F, Cl , Br etc) they are smallest in size in their respective periods. F has the smallest size in period 2 elements.
So it the most electronegative element of the period as well as group because other halogens are larger in size than F.
Similarly P , S and Cl also have tendency to gain electrons due to smaller size as compared to elements in far left of same period of periodic table.
