Answer:

Fluorine number 9

Explanation:

Fluorine has an electronegativity of 4.0 which is the highest of all elements in entire periodic table as well as the second period.

Fluorine has 9 positive protons creating an attraction for electrons the most besides Neon with 10. in the second period. Fluorine is more stable with an extra electron than it is without an extra electron. With the extra electron Fluorine achieves the same stable filled energy shell as Neon.
