The maximum number of electrons which an energy level can hold is equal to #2n^2# where #n# is the principal quantum number.

If #n=1# the maximum number of electrons = #2xx1^2=2#

So there are a maximum of 2 electrons in the #n=1# energy level.

If #n=2# the maximum number of electrons = #2xx2^2=8# electrons

If #n=3# the maximum number of electrons =#2xx3^2=18# electrons.

And so on.
