state the importance of valence electrons in the organizatin of the periodic table
Since this is not my area of expertise, I searched Google under the key words "'valence electrons' periodic table" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.
I hope this helps. Thanks for asking.
The valence electrons in an atom are the outermost electrons in the electron configuration. These electrons are important in the organization of the periodic table because they determine many of the chemical properties of an element.
The periodic table is organized based on the increasing atomic number of elements, and elements with similar chemical properties are grouped together in the same column or group. This organization is largely determined by the number of valence electrons an element has.
The number of valence electrons determines the element's reactivity, bonding behavior, and ability to form chemical compounds. Elements in the same group of the periodic table have the same number of valence electrons, resulting in similar chemical behavior.
For example, the alkali metals in Group 1 have one valence electron, which makes them highly reactive and likely to lose that electron to form positive ions. The halogens in Group 17 have seven valence electrons and are highly reactive in seeking to gain one more electron to complete their outer electron shells.
By understanding the number of valence electrons an element has, you can predict its chemical behavior, its ability to form compounds, and its contribution to the overall properties of a compound or material. Therefore, valence electrons play a vital role in the organization and understanding of the periodic table.
