Why can water have no net charge but have slight charges in different parts of the molecule?
A. The oxygen end is slightly negative and the hydrogen end is slightly positive.
B. The hydrogen end is slightly negative and the oxygen end is slightly positive.
C. The hydrogen and oxygen ends change in polarity.
D. Because it is hydrophobic.

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.

Water molecules have no net charge but have slight changes in different parts of the molecule because the oxygen end is slightly negative and the hydrogen end is slightly positive (Option A).

Water (H2O) molecules form covalent bonds between oxygen and hydrogen.

In a water molecule, the oxygen (O) atom slightly attracts electrons more strongly than atoms of hydrogen (H), thereby oxygen is more electronegative than hydrogen.

There is no net charge in a molecule of H2O, however, this molecule has polar properties and therefore can be used by biological systems as a universal solvent.

In conclusion, water molecules have no net charge but have slight changes in different parts of the molecule because the oxygen end is slightly negative and the hydrogen end is slightly positive (Option A).
