Why oxygen forms positive charge with fluorine?
Because fluorine has greater electronegativity than oxygen.
Is boron trifluoride ionic?
Yes. Fluorine has an electronegativity of 4 and Boron has an electronegativity of 2. If the difference in the electronegativity of two elements is greater than 1.8, then it is ionic.
Is calcium more electronegative than fluorine?
Fluorine is more electronegative than calcium. The electronegativity of calcium is 1. The electronegativity of fluorine is 3.98.
How does fluorine's electronegativity compare to the electronegativity of oxygen and chlorine?
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.
Which element has a higher electronegativity than nitrogen?
There are two elements. They are Fluorine and Oxygen

Is calcium more electronegative than fluorine?
Fluorine is more electronegative than calcium. The electronegativity of calcium is 1. The electronegativity of fluorine is 3.98.
Fluorine has a higher electronegativity than Lithium What does this actually mean?
electronegativity is the tendency of an atom to attract a bonding pair of electrons, therefore fluorine is more able to attract electrons then lithium (has a greater pull).
How does fluorine's elecetronegativity compare to the elecetronegativity of oxygen and chlorine?
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.
Why the bond energy of HF is greater than HBr?
Fluorine has the highest electronegativity of any element. Therefore, the energy released when hydrogen and fluorine react is greater than the energy released when hydrogen and bromine react, and that energy must be resupplied to cause either bond to break.
Why oxygen have less ionisation enthalpy than fluorine?
Oxygen has a lower electronegativity than fluorine (3.5 as compared to 4).

Is the electronegativity of fluorine more than that of hydrogen?
Yes, fluorine is more electronegative than hydrogen : it has the highest elemental electronegativity by the Allen method, at 4.193 to hydrogen's 2.300 (only neon is higher than fluorine, but it cannot be calculated using Pauling units because it forms no ordinary compounds).
Which end of the H-F bond is more negative?
The electronegativity of Hydrogen is about 2.2 and the electronegativity of Fluorine is about 4.0.Thus the negative pole is more on the Fluorine sideExtra:The difference is 1.8 which is greater than 1.7, the minimum difference for an ionic bond.So this would be an ionic bond.Or it is (at least) a very polar-covalent bond. Figures 1.7 or 1.8 are in the 'discussion' range
Fluorine is more electronegative than oxygen?
Yes it is more electro negative. F has the highest electro negativity
