atoms which have become either negatively or positively charged when their number of electrons are no longer equal to their number of protons. Atoms in such bonds can be considered polar, but only atoms in covalent bonds can be polar. Generally, ionic bonds appear between metallic atoms...

Now, a question might occur that how is ammonia polar when it has a covalent bond? To answer this, one might take the example of the bonding between a fluorine atom and a carbon atom. While ideally, the electrons should be exactly in the middle of the two bonding atoms, that is not ...
Polar molecules occurwhen two atoms do not share electrons equally in a covalent bond. A dipole forms, with part of the molecule carrying a slight positive charge and the other part carrying a slight negative charge. This happens when there is a difference between the electronegativity values of...
