Question

state the importance of shells and valance electron in modern periodic table

Answer 1

valance are important bcause with out this we may not place the elements at exact in periodic table

Answer 2

Shells and Valence electrons are important as they help us to classify the elements into the periodic table. Each row has a specific no. of shells and each element in a column has a similar valence electron configuration. This not only helps us classify them but also deduce their properties. Hence, Shells and Valence Electrons are highly important in the modern periodic table.
