A covalent bond is a bond in which electrons are shared between atoms of elements
A covalent bond is a
bond in which electrons are shared between atoms of elements. A
covalent bond can be polar or nonpolar. In a nonpolar covalent
bond, the bond is between two identical atoms and the electrons are
evenly shared between the atoms.In contrast, in a
polar covalent bond, the bond is between two nonidentical atoms and
the electrons are unevenly shared between the atoms. The uneven
sharing of electrons takes place because of the difference in the
electronegativity...

POLARITY We've already talked about electronegativity and how to predict whether a bond is polar or nonpolar. For example: Pure covalent bond = sharing of electrons between two identical atoms (with the same electronegativity and no difference in charge) i.e. O2 Polar covalent bond = sharing of electrons between two or more different atoms with a difference in electronegativity. i.e. HCI Just as a bond can be polar or nonpolar, we can also classify an entire molecule as polar or...

In a covalent bond between two atoms, the more electronegative atom will attract more electron density toward itself, producing a polar bond. The more electronegative element will carry a partial negative charge, whereas the less electronegative element will carry a partial positive charge. The direction of the bond dipole is always toward the more electronegative element. This is often indicated by an arrow, as shown in the figure. The magnitude of the bond polarity can be estimated by using the...
