A {N,n//6} QM structure periodic table with n = 1..12, and N ≤ -15 was built for the elementary particles (based on their mass, not on their sizes). The analyzed result suggested that: 1) All the down-type quarks have {N,2//6}o QM structures, while all the up-type quarks have {N,1//6}o QM structures; 2) The 1st generation of quarks may belong to {-17,n//6} QM structures, the 2nd generation of quarks may belong to {-16,n//6} QM structures, and the 3rd generation of quarks may belong to {-15,n//6} QM structures. 3) A proton (at size of {-15,1//6}) may be the ground state of both Charm quark and Bottom quark, Charm quark {-15,1//6}o may be the first excited state of proton {-15,1//6}, and the Bottom quark {-15,2//6}o may be the second excited state of proton {-15,1//6}. If it is correct, then based on this new elementary particle {N,n//6} QM structure, we may need to make some modification in the current Standard Model: Charm quark may be the 3rd (instead of the 2nd) generation of up-type quark; Top quark may be the 4th generation, although can be up-quark, but its mass fits to the down-quark much better. A new method to expand {N,n//6} QM structure periodic table from n=1..12 to n=1..36, (or even to n=1..6^3, n=1..6^4, etc.) has been proposed. This method seamlessly bridged the {N,n} QM to the classical physics.
