Polar molecule
Molecules that do not have oppositely charged ends are nonpolar molecules.
A nonpolar molecule is a molecule that shares electrons equally and does not have oppositely charged ends.
The oxygen in the water molecule is Partially negative and the Hydrogen in the water molecule is partially Positive . Thus they bond up to form Hydrogen Bond.
A molecule with partially charged areas is called a polar molecule. This occurs when there is an uneven distribution of electrons, causing one end of the molecule to have a slight positive charge and the other end to have a slight negative charge. Examples include water (H2O) and ammonia (NH3).
partially positively charged hydrogen end of the molecule.
Those molecules are polar.
partially positively charged hydrogen end of the molecule.
A nonpolar molecule is a molecule that shares electrons equally and does not have oppositely charged ends.
A nonpolar molecule is a molecule that shares electrons equally and does not have oppositely charged ends.
The ends of the water molecule have opposite electrical charges
Since water is a slightly polar molecule (the hydrogen end being slightly positive and the oxygen ends being slightly negative) the positively charged sodium ion (Na+) will be attracted to the oxygen end of the water molecule.
Molecules that have charged ends are polar. The poles are only slightly charged, so they do not have the strength of ions, so they do not form chemical bonds with one another, however they do form weak attractions with one another. Water is the classic example of a polar molecule. The oxygen atom is larger and more electronegative than the hydrogen atoms. So the oxygen end of a water molecule has a slight negative charge and the hydrogen end has a slight positive charge. The oxygen atom of one water molecule will form a weak attraction with a hydrogen atom of another water molecule. This type of attraction is called a hydrogen bond.
