Question

State the relationship between electron configuration and location of an element in the period table

Answer 1

Answer:

elements in same group have same valence electron.

period of element is equal to valence shell

Explanation:

if the elements are in a same group then they will be having same number of valence electron.

the period of an element in periodic table is equal to the valence shell of the element. that is if the valence electron are in 3 rd shell then the element will be in third period.
