:0 OMG dont tell me u dont know?! hahahaha...losser!
Fluorine is more electronegative than oxygen and chlorine. There are many scales used to measure electronegativity. Each is different. Oxygen and chlorine usually have an electronegativity value between 3.2 and 3.5 depending on the scale. Fluorine has an electronegativity of 4, the highest number on the scale. This means that the difference in electronegativity of fluorine and oxygen or chlorine is between 0.5 and 0.8 depending on the scale. This is the amount necessary to form a polar covalent bond.
Flourine
The electronegativity of oxygen is 3.44 and for fluorine it is 3.98. The difference in electronegativities is 0.54, so the bond between fluorine and oxygen is polar covalent.
Because fluorine has greater electronegativity than oxygen.
Fluorine has more electronegativity, meaning it is more "desperate" to obtain electrons. Its nucleus is the most attractive of all elements.
Fluorine has the highest electronegativity among the three elements. Oxygen is the second most electronegative, while chlorine has a slightly lower electronegativity compared to both fluorine and oxygen.

Fluorine has the highest electronegativity of any element. Its electronegativity is 4. Oxygen has the second highest electronegativity of any element, with an electronegaitivity of 3.5, and chlorine has an electronegativity of 3.16 on the Pauling scale. Note that there is more than one scale for measuring electronegativity. But no matter which scale you use, Fluorine is more electronegative than oxygen, which is more electronegative than chlorine.

FONCl (pronounced fonkle) - the order of electronegativity - F O N Cl - fluorine, oxygen, nitrogen, chlorine
The electronegativity of oxygen is 3.44 and for fluorine it is 3.98. The difference in electronegativities is 0.54, so the bond between fluorine and oxygen is polar covalent.
Because fluorine has greater electronegativity than oxygen.
The element with the highest electronegativity is fluorine (F) at 3.98 in scale. F is followed by oxygen (O) and chlorine (Cl) rated at 3.44 and 3.16 respectively.
Fluorine has more electronegativity, meaning it is more "desperate" to obtain electrons. Its nucleus is the most attractive of all elements.
Fluorine has more electronegativity, meaning it is more "desperate" to obtain electrons. Its nucleus is the most attractive of all elements.
Oxygen has a lower electronegativity than fluorine (3.5 as compared to 4).
Fluorine is more chemically similar to chlorine than it is to oxygen. Fluorine and chlorine both have 7 valance electrons, whereas oxygen has 6.
