Answer 1

Answer:

Atoms of period 3 elements must: have full K shells (2 electrons in the first energy level) have full L shells (8 electrons in the second energy levels)32 electrons

In K, L,M, N shells,in the N shell it can accommodate 32 electrons 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.
