Discuss whether the following statement is correct: “An ionic bond can, in principle, be thought of as a very polar covalent bond. Polar covalent bonds, then, fall somewhere between ionic bonds at one end of the spectrum and nonpolar covalent bonds at the other end.”

- The “octet rule” in chemistry helps predict the types of bonds thatatoms will form. In general, an atom will be most stable if it fills itsouter shell of 8 electrons.
