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.
What else can I help you with?
Is Na and F a polar or nonpolar bond?
The bond between Na and F is considered polar. Sodium (Na) is a metal, while fluorine (F) is a nonmetal with higher electronegativity. This difference in electronegativity leads to an uneven sharing of electrons in the bond, making it polar.
What bond will be expected to be more polar As Cl or As F?
The As-F bond will be more polar than the As-Cl bond. This is because fluorine is more electronegative than chlorine, leading to a greater difference in electronegativity between the atoms and a more polar bond.
Is an N F bond expected to be more polar than an 0 F bond?
The electronegativity of N O and F are 3.0 3.5 and 4 respectively according to the Pauling's scale. The electronegativity difference between N and F is greater than the difference between O and F. So, the prior bond is expected to be more polar.
Which is the more polar bond o-s o-f?
The O-F bond is more polar than the O-S bond. This is because fluorine (F) is more electronegative than sulfur (S), leading to a greater difference in electronegativity between oxygen (O) and fluorine compared to oxygen and sulfur, resulting in a more polar bond.
Which of these bonds are most polar H-Cl H-Br H-F?
The H-F bond is the most polar because fluorine is the most electronegative element among chlorine, bromine, and fluorine. The greater the electronegativity difference between the elements in a bond, the more polar the bond.
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 Na and F a polar or nonpolar bond?
The bond between Na and F is considered polar. Sodium (Na) is a metal, while fluorine (F) is a nonmetal with higher electronegativity. This difference in electronegativity leads to an uneven sharing of electrons in the bond, making it polar.
What bond will be expected to be more polar As Cl or As F?
The As-F bond will be more polar than the As-Cl bond. This is because fluorine is more electronegative than chlorine, leading to a greater difference in electronegativity between the atoms and a more polar bond.
Is an N F bond expected to be more polar than an 0 F bond?
The electronegativity of N O and F are 3.0 3.5 and 4 respectively according to the Pauling's scale. The electronegativity difference between N and F is greater than the difference between O and F. So, the prior bond is expected to be more polar.
Which is the more polar bond o-s o-f?
The O-F bond is more polar than the O-S bond. This is because fluorine (F) is more electronegative than sulfur (S), leading to a greater difference in electronegativity between oxygen (O) and fluorine compared to oxygen and sulfur, resulting in a more polar bond.
Which of these bonds are most polar H-Cl H-Br H-F?
The H-F bond is the most polar because fluorine is the most electronegative element among chlorine, bromine, and fluorine. The greater the electronegativity difference between the elements in a bond, the more polar the bond.
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.
Is the H-F bond polar?
The bond between hydrogen and fluorine is polar covalent.
Would Na and F form a polar covalent bond?
Yes, Na and F would form an ionic bond rather than a polar covalent bond. This is because Na tends to donate one electron to F, resulting in the formation of Na+ and F- ions which are held together by electrostatic attractions.
Is ClF4- polar or non polar?
There are two allowed structures of SF4Cl2... the cisform where one chlorine is in an equitorial position and one is axial, and the trans form where both chlorines are in axial positions. In the trans form the S-F bond dipoles all cancel each other, as do the S-Cl bond dipoles, because they are opposite each other. Therefore the molecule is non-polar. In the cisform, two of the S-F bond dipoles cancel, but because the other S-F bond dipoles are across from S-Cl bond dipoles, they do not cancel (S-F is more polar than an S-Cl bond). Therefore, the cisform is polar.
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.
