Question

number of electrons present in each Uni Negative Ion of an element with highest electronegativity in periodic table is?​

Answer 1

Answer:

the most electronegative element. Fluorine has an electronegativity of 3.98 on the Pauling Electronegativity Scale and a valence of 1.A fluorine atom needs one electron to fill its outer electron shell and achieve stability, which is why free fluorine exists as the F- ion. Other highly electronegative elements are oxygen and chlorine. The element hydrogen does not have as high of an electronegativity because, although it has a half-filled shell, it readily loses an electron rather than gains one.the halogens are most electronegative in there respective periods.
