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.
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.
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.
Those molecules are polar.
A nonpolar molecule is a molecule that shares electrons equally and does not have oppositely charged ends.
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.
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.
If you are talking about covalent bonded molecules, then you would call them polar molecules. This means one element is hogging the shared electrons more than the other. This would make one element partially charged positively, and the other element partially charged negatively The signs to show partially charged looks like an incomplete 8.
