Polar Molecule
Polar Molecule
A molecule with an uneven distribution of charge, creating a positive and a negative side, even though the overall molecule is neutral.
Neutral Molecule
Neutral Molecule
A molecule where the charges are evenly distributed, resulting in no net positive or negative charge.

Study Notes
Polar Molecules
- A polar molecule is a molecule that has a permanent electric dipole moment, resulting from an uneven distribution of electrons within the molecule.
Characteristics of Polar Molecules
- Polar molecules have a slightly positive charge on one end and a slightly negative charge on the other end.
- This uneven distribution of electrons creates a permanent electric dipole moment.
Object that Can be Described as an Ion
- An ion is a charged particle that can be formed when an atom gains or loses electrons.
Difference Between Polar and Non-Polar Molecules
- Polar molecules have a permanent electric dipole moment, while non-polar molecules do not.
- Non-polar molecules have a symmetrical shape, resulting in a uniform distribution of electrons.
Neutral Molecules
- A neutral molecule is a molecule that does not have a permanent electric dipole moment.
- Neutral molecules have a symmetrical shape, resulting in a uniform distribution of electrons.
Examples of Polar Molecules
- Water (H2O) is an example of a polar molecule due to its bent shape, which results in an uneven distribution of electrons.
Importance of Polar Molecules
- Polar molecules play a crucial role in many biological and chemical processes, as they are capable of forming hydrogen bonds and ionic bonds.
Note on Polar Molecules
- The polarity of a molecule determines its ability to dissolve other substances and participate in chemical reactions.
