Water is an example of a polar molecule; the oxygen end has a slight negative charge whereas the hydrogen ends are slightly positive. Oxygen is electronegative because it only needs 2 electrons to complete it's valence shell. Instead of losing an electron (like sodium, in sodium chlorine), it simply attracts to those 2 electrons. Developments in Dynamic Covalent Chemistries from the Reaction of The total mass of hydrochloric acid and sodium hydroxide will result in a lower total mass of sodium chloride and water. A. Covalent bonds are formed when atoms share one or more electrons. An atom of oxygen and two atoms of hydrogen form water molecules by means of polar covalent bonds.
