Why is the third shell of an atom not full completely with 18 electrons?

a shell can only have 8 electron to attain noble gas or for its stable electronic configuration it is according to lewis structure
but if we see correctly the shell has sub shells
s , p , d , f orbitals
s can hold 2 electrons
p can hold 6 electrons
d can hold 10 and f 14 electron these are their maximum capacity
and when shell 3 is fully filled
it is of the form 1s^2 2s^2 2p^6 3s^2 3p^6 3d^10
first one is 2 and adding next 2 is 8 and
if you add the last three you will get 18
E.C = 18

prakhargupta3301:
But why is that? If the shell has a capacity of sustaining 18 electrons, why doesn't it becomes stable when it has all 18? why just 8?
which std your studying
9th. Why?
You didn't answer
you will learn much more in 11th
can you understand
Looks like I still dont get it XD. I guess I would have to ask my teacher about it. Thanks for the help thou! You are great!
your welcome
