As fluorine's atomic number is 9, it possesses 7 valency electrons of valency shell 2s^2. 2p^5 so only one more electron is needed to get stability according to octet rule. So, fluorine is the most electronegative element,and the second most electronegative element is oxygen.

Flurone has high electronegetivity because if we move from left to right in periodic table electronegativity increases.

Because it needs one more electron to complete its octet state and that is why it is an electronegative element. It is also because it reactive state of accepting electron.

Because fluorine accepts electrons and d most reactive non metal in the Halogens family.

Flourine is the most electro negative among them.

Because in the outermost shell, there are 7 elections.

So to become stable it required only 1 election.
So it gains 1 electron from any atoms who has extra 1 electron.

Though flourine required 1 electron, it becomes F". Or ELECTRO NEGATIVE.

Fluorine is the correct answer.

Electronegativity increases across a period(left to right) and also decreases down a group.

So the general trend is diagonally across the periodic table from left to right(excluding the noble gases).

Fluorine is the most electronegative element and also the most reactive non-metal.

Because fluorine is the only element that accepts 1 electron to complete its outermost shell therefore making it highly electronegative.

Because the fluorine atom is small in size.

Fluorine is more electronegative because it gains one electron to be stable.

Fluorine is more electronegative because its ion is -1 while oxygen is -2. The lesser the electronegative charge the more electronegativity.
