In addition to the good post from Chemistry4me: they are called "shell" for simplicity but there is not an exact correspondence with distance from the nucleus and so with order of filling.
For example, you could say, for the sake of simplicity, that a tree trunk is lower than the foliage, but actually they are someway 'mixed'.

Potassium has 19 electrons
Electronic configuration is 
1st shell - 2 electrons 
2nd shell - 8 electrons
3rd shell - 8 electrons
4 th shell - 1 electron
Due to its electronic configuration its consists 1 electron in its 4th shell

ajimonmathaip2v16a: Then 3rd shell include 18 electrons. Then why One electron in the forth shell
