All bonds are polar unless they are two of the same element because of the electronegativity of the atoms. The side with the more electronegative atom is the negative side because it pulls electrons closer to it than a less electronegative atom. The periodic trend of elecronegativity increases left to right across the table and decreases up to down. Hope this helps..
What else can I help you with?
How must the electronegativies of two atoms compare if a covalent bond between themis to be polar?
The electronegativities must be far enough apart to be polar. If one atom has a 2.1 and the other a 4 electronegativity, then the molecule is polar. However, a 2.1 and a 2.3 would be close enough for uniform electron density.
Is SF4 covalent?
CF4 is a covalent bond, because both elements are "nonmetals"
What would have to be the case for a bond to be non-polar covalent?
For a bond to be non-polar covalent, the two atoms involved in the bond would have to have the same electronegativity, so the ∆EN (difference in electronegativity) is zero. An example would be F2 or Cl2 where two halogen atoms bond together, and the ∆EN is zero.
What is the type of bond between H plus O?
Oxygen cannot bond with a single Hydrogen atom naturally. It must bond with two in order to become stable again. This is known as water, or H2O. However, another bond is possible known Hydrogen Peroxide, or H2O2. As there is an extra Oxygen atom the molecule is less stable and therefore more acidic than water. Hence it's use as an anti-septic.
What type of bond is PBr?
PBr is a polar covalent bond. To figure this out you must you an Electronegativity Table. On this table Br=2.8 and P=2.1. Subtract and you get .7. If your answer (in this case .7) falls between .5 and 1.9, then you have yourself a polar covalent bond.
What type of chemical bond must be present for must chemists to define molecules?
A covalent bond, (polar or non-polar)

Is NaCl polar covalent?
To classify a bond as polar or covalent, you must first find the Electronegativity difference. The electronegativity of Na is 0.93 and Cl is 3.16. Therefore we find the electronegativity difference by subtracting: 3.16 - 0.93= 2.23. Therefore NaCl is an ionic bond. For electronegativity differences >1.7, the bond is ionic. For electronegativity differences between 0.4-1.7, the bond is polar covalent For electronegativity differences < 0.4, the bond is non-polar covalent.

What type of bond must be present for most chemists to define molecules?
"covalent" OR "covalent bond"

What happens when atoms form a covalent bond?
a) Must include a metal and a nonmetal b) Must be of different elements c) Are always of the same element d) Are always two metals Need Answer! :( D) Are always two metals. a) is for ionic compounds b) is for nonpolar covalent bonds c) same as nonpolar covalent bonds b) Must be of different elements:)

How do you calculate electronegativity difference to determine the type of bond must know values for each type of bond?
you subtract the largest EN from the smallest and then look @ the number if its... 0-0.5 its Pure covalent 0.5-1.7- Polar covalent 1.7-3.3 its Ionic bond good luck :) lol idk a word ur sayin
We further separate covalent bonds into polar covalent and nonpolar covalent what would have to be the case for a bond to be a nonpolar covalent?
For a bond to be nonpolar covalent, the two atoms involved must have similar electronegativities, meaning they share the electrons equally. This leads to a symmetrical distribution of charge, resulting in a nonpolar molecule. Bonds between identical atoms (diatomic molecules like oxygen gas, O2) are examples of nonpolar covalent bonds.
Is O and F considered covalent ionic or neither?
The words "covalent" and "ionic" refer to bonds between atoms, and not atoms themselves. If you are referring to O2 and F2, the forms in which we find oxygen and fluorine, respectively, then the bond between the two oxygens is considered to be non-polar and covalent. The same can be said of the bond between the two fluorine atoms in F2. If you are referring to the bonds in the compound formed by oxygen and fluorine, you must first identify that compound. It is OF2, and is named "fluorine oxide". The bonds between the oxygen and fluorine in fluorine oxide are slightly polar and covalent. The determining property is "electronegativity", which you should look up and review. By convention, when the electronegativity difference between atoms is: < about 0.4, the bond between them is non-polar and covalent between about 0.4 - 1.7, then bond between them is polar and covalent > 1.7, then bond between them is ionic.
