Q:

was the octet rule disproven? 

so according to my understanding orbitals can hold s can hold 2 electrons and p can hold 8 electron d hold 18 and f can hold 32.  wouldn't this violate the octet rule?  which say only the first shell can hold 2 electrons and the rest of the shells 8.  im also confused why some websites says that each orbital has 2 electrons, s has 1 orbital  (2 electrons) p has 3 orbitals (6 electrons) d has 5 (10 electrons) and f has 7 orbits ( 14 electrons)
im so confused guys plz help me as simple as possible 

A:

The octet rule has no theoretical basis.  It has been observed to work quite often.  But that is all we could say.  It cannot be proven.  The octet rule works nearly perfectly in organic chemistry,
There are many examples where this rule is not verified.  For example the Boron hydrides, the simplest being $B_2H_6$. This compound is commercial, but it does not follow the octet rule.  Another example is the familiar molecule of Oxygen $O_2$, which has no double bond as often given in elementary chemistry courses.  Other examples : $PCl_5, SF_6$. Another simple example is Nitrogen oxide $NO$. And a lot of compounds made with metals from the transition range.
