Question

How does the electronic configuration of atoms relate to its positive in the modern periodic table

Answer 1

Electronic configuration do tell us about the position of the element. The valence eleatron or the electron in last shell tell us about the group number as elements having group 1and 2 would have valence electron 1or 2. To find the group of elements after 13 just add 10 in the valence electron. Now the number of shells tell its period number.

Answer 2

Explanation:

In the modern periodic table, atoms with similar electronic configurations are placed in the same column. In a group, the number of valence electrons remains the same.

Elements across a period show an increase in the number of valence electrons.
