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.

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

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.

Because the fluorine atom is small in size.

Fluorine has more electronegative than other element because its small in size.

When we go to the left to right in periodic table atomic sizes are decrease and electro negativity are increase.

Because an electron gain enthalpy and becomes more nagative from left to right.

Addition of an electron in 2p-orbital leads to a greater repulsion when atomic size is very small as in f.
