While going to the right side the size of the atom is decreasing, hence the size of the oxygen is higher than fluorine. Also to obey the octet rule fluorine needs one more electron. All these makes fluorine more electronegative than oxygen.

Florine is most electronegativity due to small size. In periodic table going to left to right atomic size decreases & electronegativity increases. As we move right to left of periodic table EN decreases then atomic size increases.

Flourine is the most electron nagetive, because it has 7 valence electron in its outmost shell and need 1 electron to gain an octet structure, this makes it to react easily with the alkaline metal of group 1 elements and other metals.

Electronegativity is high in non-metals than in metals flourine is the most electronegative because it's a non-metal, it has 7electrons in it outer most shell and can easily accept 1 electron to obtain an octet state.

Because fluorine is halogen and all halogens are more electronegative. (2) it obeys octet rule and from its electronic configuration 1 electron is less to cmplt da octet. So it is electronegative.

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.

Atomic no of florine is 9 its configuration is 2, 7 outermost shell contain 7 electrons it is easy to gain one 'e' to complete its octect. That's why it is more electronegative element.

Because of presenting in the halogen group it having the higher electron negativity. Fluorine is in small size so it wants only one electron for this it is the strong oxidizing agent.
