Summaries the rules for writing of distribution of electrons in various shells for the first eighteen elements.
 
a. The maximum number of electrons present in a shell is given by the formula
Where, n is . \(n = 1, 2, 3, 4,\) etc. Therefore, the maximum number of electrons in different shells are as follows:
 
Energy
levels
Shells
Electron
capacity
1
\(K\)
 
2
\(L\)
3
\(M\)
4
\(N\)
 
b. The maximum number of electrons that can be accommodated in the outermost orbit is .
c. Electrons cannot fill in a given shell unless the inner shells are filled. In other words, the shells are gradually filled. The size of the nucleus is very small as compared to the atom.
