Please help! Is this statement true or false? What's true and false, and why?

How is this statement true or false, and to what extent:


';All strong and weak chemical forces result from the attraction of opposition charges, therefore they are all approximately the same strength.';Please help! Is this statement true or false? What's true and false, and why?
false. All attractions are not necessarily between oppositely charged particles. You may find covelent bonds which are formed due to sharing of pair of electrons. And metallic bonds due to collective sharing of free electrons.Please help! Is this statement true or false? What's true and false, and why?
False...





For example, van der waals forces (aka london forces) between the electrons of one molecule and the protons of the other molecue is MUCH weaker than hydrogen bonding forces.
