Question

find the maximum electron capacity of K, L, M, shells

Answer 1

Each shell can contain only a fixed number of electrons: The first shellcan 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 shellcan in principle hold up to 2(n2)electrons.
