Here's why:
* Electronegativity: Fluorine is the most electronegative element on the periodic table. This means it has a strong attraction for electrons.
* Sharing Electrons: When two fluorine atoms come together, they both have a strong desire to gain an electron to achieve a stable octet. Instead of one atom completely taking an electron from the other, they share a pair of electrons equally. This creates a nonpolar covalent bond.
