Distribution of electrons in different shells of an atom​

Answer»

Answer:

Each shell can contain only a fixed number of electrons: The FIRST shell can HOLD up to two electrons, the SECOND shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The GENERAL formula is that the nth shell can in principle hold up to 2(N2) electrons.
