We were told that maximum number of electrons in the last shell is given by the formula 2n2 . But we were also told it at the maximum number of electrons the last I can accommodate is 8.But acoording to the formula 3rd shell can accomodate 18 electrons. Please explain

Please read the complete solution.
The maximum number of electrons that can be accommodated in a shell is given by the formula 2n², where n denotes the shell number.
Thus, since for the K shell, n = 1, hence the maximum number of electrons that can be accommodated in the K shell is 2 X (1)2 = 2.
Similarly, the L shell can accommodate a maximum of 8 electrons, while the M and the N shell can accommodate a maximum of 18 and 32 electrons respectively.
If, however, a given shell is the outermost shell, it cannot hold more than 8 electrons. For example, the M shell can hold a maximum of 18 electrons, but if it is the outermost shell, then it cannot hold more than 8 electrons. Similar is the case with the N shell. It has the capacity to hold maximum of 32 electrons. But if it is the outermost shell, then it cannot hold more than eight electrons.
Hope this helps.
Good luck.
