CBSE - IX - Chemistry - Structure of the Atom

Respected Sir/Madam,
We have the formula 2 n squared where n is no. of shell which gives us the maximum no. of electrons the shell can accomodate . If an atom has 5 shells then the outermost shell will have 50 electrons according to the formula 2 n squared but this contradicts the rule that outermost shell can only have maximum no. of  8 electrons. Please explain...

Answer:

The fifth energy shell has 50 electrons (s, p, d, f, g subshells). 
p subshell = 6 electrons
d subshell = 10 electrons
f subshell = 14 electrons
g subshell = 18 electrons
Hence total 50 electrons in the fifth energy level, which confrms 2n2 formula.
