Helium (He) is an inert element/noble gas and does not form bonds with other elements. Helium and fluorine (F) would therefore not form any kind of bond.
Some of the noble gases have been coerced into forming compounds (xenon and krypton in particular), but thus far none are known for helium. It's theoretically possible that at very low temperatures and extreme pressures, stable helium compounds could exist, and the stable cation HeH+ is known to exist.

∙ 14y agoThe bond between He & F doesn't exist, because Helium is a noble gas (it has 8 electrons in its outer shell)

Is cf3cl polar?
CF3Cl is a polar molecule. There are three C-F polar bond and and C-Cl polar bond. The bond dipoles do not cancel out and hence the compound is a polar molcule.
Is cf3cl polar or nonpolar?
CF3Cl is a polar molecule. There are 3 C-F polar bond and 1 C-Cl polar bond. Since the difference in electronegative between C and F is not the same as that of C and Cl, therefore their bond polarities are not the same which results in the compound is a polar molcule.
Which is a more polar bond n-f or n-br?
N-F is more polar. 100% positive
Does HF have a polar covalent bond?
yes it is a polar covalent bond. the difference of electronegativities of H and F is 1.9 , it should be an ionic bond but the ratio of atomic sizes of both the atoms is responsible for polar covalent bond.
Would Na and F form a polar covalent bond?
No, they would form an ionic bond.
Is the H-F bond polar?
The bond between hydrogen and fluorine is polar covalent.
Is F-F ionic or covalent bond?
The F-F bond (in F2) is covalent, and non polar covalent at that.
Why the H-F bond is expected to be more polor than the H-I bond?
The H-F bond is more polar than the H-I bond because F (fluorine) is more electronegative than I (iodine). It thus attracts the shared electrons more than does the I, making it a more polar bond.
Is cf3cl polar?
CF3Cl is a polar molecule. There are three C-F polar bond and and C-Cl polar bond. The bond dipoles do not cancel out and hence the compound is a polar molcule.

Which is a more polar bond n-f or n-br?
N-F is more polar. 100% positive
Is IF polar or non polar?
yes it is the bond is polar, and the linear shape allows for polarity, F is negative
Does HF have a polar covalent bond?
yes it is a polar covalent bond. the difference of electronegativities of H and F is 1.9 , it should be an ionic bond but the ratio of atomic sizes of both the atoms is responsible for polar covalent bond.
Would Na and F form a polar covalent bond?
No, they would form an ionic bond.
Would N and F form a polar covalent bond?
The electronegativities of nitrogen and fluorine are considerably different. Therefore they make a polar covalent bond.
Is FCH3 a nonpolar molecule?
No. It is a polar molecule.
Is ammonium fluoride is ionic or polar covalent bond?
NH4 + and F - Form the ionic bond, NH4F ------
