2. Polar Molecules Chemical bonding is the result of either an atom sharing one or more electrons with another atom or an atom taking outer orbit electrons from the atom with which it is bonding.

3. Let’s take a look at water Water is a polar molecule because of the way the atoms bind in the molecule such that there are excess electrons on the Oxygen side and a lack or excess of positive charges on the Hydrogen side of the molecule. Water is a polar molecule with positive charges on one side and negative on the other

4. Non Polar Molecules A non-polar molecule is one that the electrons are distributed more symmetrically and does not have an abundance of charges at the opposite sides. The charges all cancel out each other. The charges in non-polar Carbon Dioxide are evenly distributed The charges in no- polar Carbon Dioxide are evenly distributed

5. What does this mean? Atoms in polar molecules is such that one end of the molecule has a positive charge and the other side has a negative charge. Non-polar molecules do not have charges at their ends. Mixing molecules of the same polarity usually results in the molecules forming a solution.
