How do you appreciate the role of electronic configuration of the atoms of elements in periodic classification?(OR) How does electronic configuration help in the classification of elements in modern periodic table? |
|
Answer» The quantity is electronic configuration. 1. Modern periodic table is based on electronic configuration. So elements are arranged in ascending order of their atomic numbers. 2. The chemical properties of elements depend on valence electrons. The elements in same group have same number of valence electrons. So the elements belonging to same group have similar properties. 3. So the construction of modern periodic table mainly depends on electronic configuration. 4. Thus electronic configuration plays a major role in the preparation of modern periodic table. So its role is thoroughly appreciated. |
