Molecules that have an unequal distribution of electrons are calle
Polar molecules
A molecule with an uneven distribution of charge is said to be a polar molecule. A polar molecule, because of an uneven distribution of charge, basically has an "end" that is slightly more positive and another that is slightly more negative. Let's look at an example.The water molecule is a good example of a polar molecule. It's oxygen end is a bit more negative, and the end with the pair of hydrogen atoms on it is slightly more positive. That gives the molecule an overall "endedness" with a positive and a negative end.
Polar molecules have positive charge on one side and negative charge on other side. Non polar molecules have covalent bond and do not have positive and negative charge on one or other side of the molecule.
Because of the unequal sharing of electrons. As in H2O, Hydrogen has a positive charge and Oxygen has a negative charge.
A chemical bond with unequal sharing of electrons is called a covalent bond. This results to a slightly negative charge on one end and a slightly positive charge on the other end.
The electrical charge is unequal distributed in the water molecule.

unequal sharing
No. Hydrogen bonds form as a result of highly unequal charge distribution.
Polar molecules have positive charge on one side and negative charge on other side. Non polar molecules have covalent bond and do not have positive and negative charge on one or other side of the molecule.

Polar molecules have unequal distribution of electrons. Water for example, oxygen is more electronegative than hydrogen so it will pull electrons towards itself, giving oxygen partial negative charge on it and partial positive charge on the hydrogen. A hydrogen bond forms between the partial negative charge on oxygen on another water molecule and partial positive charge on hydrogen on other water molecule.
An atom that does not have a neutral charge is called an ion. It has an unequal number of protons and electrons.
A chemical bond with unequal sharing of electrons is called a covalent bond. This results to a slightly negative charge on one end and a slightly positive charge on the other end.
Atoms with unequal numbers of protons and electrons are called ions. In general, an ion is a charged particle, and if we have any atom that has an unequal number of protons and electrons, it has a charge imbalance, and will have an overall net charge. This charge will be positive if the number of electrons is less than the number of protons, or it will be negative if the number of electrons is more than the number of protons. In either case, that atom will end up with an overall net charge (either positive or negative) and will be considered an ion. Lastly, an anion is an atom with a negative electrical charge (a negative ion), and a cation is an atom with a positive electrical charge (a positive ion).ions.
