Polarity of a Water Molecule. Water (H2O) is polar because of the bent shape of the molecule. The shape means most of the negative charge from the oxygen on side of the molecule and the positive charge of the hydrogen atoms is on the other side of the molecule. This is an example of polar covalent chemical bonding.
In this way, what does it mean to say water is a polar molecule?
Water is a "polar" molecule, meaning that there is an uneven distribution of electron density. Water has a partial negative charge ( ) near the oxygen atom due the unshared pairs of electrons, and partial positive charges ( ) near the hydrogen atoms.
What is the cause of a polar molecule?
The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms. When a neutral molecule has a positive area at one end and a negative area at the other, it is a polar molecule.
How are polar molecules attracted to each other?
Some molecules have positive and negative ends too, and when they do, we call them polar. Things that are polar can attract and repel each other (opposite charges attract, alike charges repel). The two magnets in the image above will attract because their opposite poles are near.
