A polar bond is a covalent bond in which there is a separation of charge between one end and the other - in other words in which one end is slightly positive and the other slightly negative. Examples include most covalent bonds.

Apr 16, 2023 · Once an atom is polarized, it forms an induced dipole. A "dipole" is a pair of equal and oppositely charged particles. In this case, these particles are comprised of the nucleus (which is positively charged) and the electron cloud (which is negatively charged).
Jun 29, 2017 · The polarisability is a measure of how an atom's electrons can be displaced from equilibrium by a nearby electric field. The polarisability is approximately inversely proportional to the ionisation energy (taken across periods in the periodic table); the easier it is to ionise the easier it is to alter the average electron's positions because ...
- Fluorine is not very polarizable because it is small. Its electrons, therefore, are all close together. A polarized atom has shoved all its electro...
- It is not true that the strength of a bond is inversely proportional to the polarisability of the atoms involved in the bond. Bond strength involve...
Jul 16, 2020 · In polar covalent bonds, the electrons are shared unequally, as one atom exerts a stronger force of attraction on the electrons than the other. The ability of an atom to attract a pair of electrons in a chemical bond is called its electronegativity.
You have a little bit of negative charge on one side, a little bit of positive charge on the other side. So it's still a covalent bond, but it's a polarized covalent bond due to the differences in electronegativities between those two atoms.

Dec 10, 2023 · A nonpolar covalent bond is one in which the electrons are shared equally between two atoms. A polar covalent bond is one in which one atom has a greater attraction for the electrons than the other atom. If this relative attraction is great enough, then the bond is an ionic bond.

This results in the spherical non-metal anions becoming oval or egg shaped, we say they are polarised (polarised simply means that the electron density around an atom has been squashed or stretched or distorted in some way).
