How does the electronic configuration of an atom relate to its positio

1.	How does the electronic configuration of an atom relate to its position in the periodic table?
Answer» Read it and after that see in the period table The electronic configuration of elements and their position in the periodic table are related to each other. From the electronic configuration of elements, we can determine the period and group to which the elements belongs.Consider sodium with atomic number 11. K,L and M shells have 2,8 and 1 electron each. Since there are 3 principal energy levels, sodium belongs to third period.M shell (valence shell) has only 1 electron. So sodium belongs to group 1 or IA
