GEOLOGY

Detailed explanation-1: -A polar covalent bond is a covalent bond in which the atoms have an unequal attraction for electrons and so the sharing is unequal. In a polar covalent bond, sometimes simply called a polar bond, the distribution of electrons around the molecule is no longer symmetrical.

Detailed explanation-2: -What do we call a covalent bond where electrons are shared UNEVENLY or UNEQUALLY? Ionic.

Detailed explanation-3: -A bond in which electrons are shared unevenly is known as a polar bond. Much like the poles on a mini magnet, the atoms connected by a polar bond become positive and negative poles.

Detailed explanation-4: -The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles-a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side). We say that the water molecule is electrically polar.
