Answer – Fluorine is the most electronegative element in the periodic table.
Explanation:
Fluorine’s electronegativity is measured at 3.98 on the scale. Its high electronegativity also makes it extremely reactive, making way for reactions with just about any element or compound. There are two reasons for this. The property of electronegativity is said to increase from left to right in the periodic table, along with increasing from bottom to top. Without considering the unreactive noble gasses, Fluorine occupies the topmost point in the rightmost corner of the periodic table. Another explanation for its electronegativity is concerned with the electrons in its outermost 2p orbital. With 5 electrons in the external shell, Fluorine’s 2p orbital is only 1 electron short of reaching the ideal gas configuration, where the outermost shell is fully occupied by 6 electrons. To ensure its valence shell is filled, Fluorine remains highly reactive and seeks a stable state.
