The more electronegative an atom is the more "pull" the atom will have on the electrons in the molecules. For example, water (H2O) contains the very electronegative atom Oxygen. Oxygen would pull more electrons toward it so the hydrogen would essentially lose their electrons. The dipole moment would point towards the oxygen. Therefore, the more electronegative an atom is the more the dipole moment will point in its direction therefore affecting polarity of the bond.

The more electronegative atom will make its end of the bond more negative.

∙ 11y agoWhat is key is the difference between the electronegativities of the atoms involved. When the difference is approximately 2 or more the bond is ionic if it is less than 1.7 then it will be covalent and in that case the greater the difference the more polar the bond will be. For example fluorine the most electronegative element forms a non polar bond in the fluorine molecule, and ionic bonds with metals.

∙ 8y agoIf the difference between electronegativities is not so important a covalent polar bond is formed.
If the difference between electronegativities is important an ionic bond is formed.

∙ 7y agoIt isn't so much the electronegativity per se, but more the DIFFERENCE in electronegativity between the two atoms involved in the bond. The greater the difference, the more polar will be the bond, and the more ionic character that bond will have. The opposite is also true. When the electronegativity difference is small, the bond is not very polar, and it has more covalent character.

What are two atoms does hydrogen bonding occur?
FON The atoms that hydrogen bonds to when hydrogen bonding occurs, due to electronegativity variance, are; Fluorine Oxygen Nitrogen
Is O2 is an example of a nonpolar polar or ionic?
Non polar covalent bonding. (Both atoms have the same electronegativity)
What does bonding is on a continuum mean?
To say that bonding is on a continuum means that the type of bonding changes gradually as the difference in electronegativity between atoms increases. There is no sharp distinction between polar covalent and ionic bonds.
How does electronegativity help us determine if a bond is pure covalant bond or polar covalent?
Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.therefore If the atoms are equally electronegative, both have the same tendency to attract the bonding pair of electrons, and so it will be found on average half way between the two atoms. if the atoms have different electronegativity there is partial polar difference as a resat of this there is a pole.by this polarity we concluded this is pure covalent bond or not .NOTE:No electronegativity difference between two atoms leads to a pure non-polar covalent bond.A small electronegativity difference leads to a polar covalent bond.A large electronegativity difference leads to an ionic bond.
Which type of bonding is usually exhibited when the electronegativity difference between two atoms is 1.1?
If electronegativity difference is between 0.3 and 1.7 then the bond tends to be is polar. This, however, does not mean that the molecule itself is polar.
What are two atoms does hydrogen bonding occur?
FON The atoms that hydrogen bonds to when hydrogen bonding occurs, due to electronegativity variance, are; Fluorine Oxygen Nitrogen
What is required for a bond to be polar?
The bonding atoms/ions should have different values in electronegativity.
What are the rules for determining if a compound is covalent?
The electronegativity difference between the bonding atoms is concerned to determine it ionic behaviour.
Why is the bonding in O2 molecules called pure covalent?
because there is no electronegativity difference between the two oxygen atoms.
Is O2 is an example of a nonpolar polar or ionic?
Non polar covalent bonding. (Both atoms have the same electronegativity)

Does metallic bonding occur between atoms of copper or chlorine?
Metallic bonding occurs between copper atoms. Only copper is a metal and has the characteristics needed for metallic bonding. Metallic bonding occurs between atoms with low electronegativities (low tendency to attract electrons from other atoms) and low ionisation energies (little energy required to remove electrons from the atoms). The low tendency for the metallic atoms to keep their electrons allow their electrons to be shared between the atoms, which thus become cations. The cations tend to be very closely-packed; they are not repulsed by their similar positive charges, but attracted to the electrons flowing freely between the cations. Metallic bonding therefore occurs between copper atoms, which have low electronegativity and ionisation energy. Chlorine atoms have some of the highest electronegativity and ionisation energy of all elements, and thus do not exhibit metallic bonding.

If electronegativity difference is between 0.3 and 1.7 then the bond tends to be is polar. This, however, does not mean that the molecule itself is polar.
Which is involved in hydrogen bonding?
electronegativity
What large differences in electronegativity result in bonding between atoms?
If this difference is under 2 the bond is covalent; if the difference is over 2 the bond is ionic.
Explain how can you calculate the Energetics of Covalent Bonding and the Ionic character?
To calculate the the Energetics of Covalent Bonding and the Ionic character, you need to take into accot the difference in electronegativity of two atoms: Δχ = χB − χA.
