Book Free DemoSummaries 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.
