Polar atoms occur when different atoms are bonded within the molecule, such as carbon dioxide (CO2) and water (H2O), where the pull of certain atoms cause the electron distribution to become unequal. If the molecule has more than one element contained, then the atoms are polar.

What does an atom being polar mean?
A bond between two or more atoms is polar if the atoms have significantly different electronegativities (>0.4). Polar bonds do not share electrons equally, meaning the negative charge from the electrons is not evenly distributed in the molecule.

Can an atom be polar and nonpolar?
Key Takeaways: Polar and Nonpolar Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out.

How do you know if an atom is polar?
To summarize, to be polar, a molecule must:
Draw the Lewis structure.
Figure out the geometry (using VSEPR theory)
Visualize or draw the geometry.
Find the net dipole moment (you don't have to actually do calculations if you can visualize it)
If the net dipole moment is zero, it is non-polar. Otherwise, it is polar.

What makes an atom nonpolar?
Nonpolar Covalent Bond. A bond between 2 nonmetal atoms that have the same electronegativity and therefore have equal sharing of the bonding electron pair. Example: In H-H each H atom has an electronegativity value of 2.1, therefore the covalent bond between them is considered nonpolar.

Chlorine has a higher electronegativity than hydrogen, but the chlorine atom's attraction for electrons is not sufficient to remove an electron from hydrogen.
Polar molecules must contain one or more polar bonds due to a difference in electronegativity between the bonded atoms. Molecules containing polar bonds ...
For example, the Cl2 molecule has no polar bonds because the electron charge is identical on both atoms. It is therefore a nonpolar molecule. None of the bonds ...
