How do you appreciate the role of electronic configuration of the atoms of elements in periodic classification ?

Explanation

1 ) Moseley , By analysing the X - ray patterns of elements of elements realized to use electronic condiguration to Classify elements .
2 ) The correlation between X - ray spectra anatomic number indicated that an element is characterised by its atomic number and not by atomic mass .
3 ) The properties of elements are dicated by its atomic number of its electrons , specifically by their arrangement outside the nucleus .
4 ) Hence Moseley chose electron configuration for classification of elements .
5 ) This Classification rectffied all the short comings of Mendeleeff's classfifcation and also enabled the study of physical and chemical properties of elements easily
6 ) The place of an element in the periodic table can be easily identified with the help of electron configuration so that all properties can be studied easily .
7 ) Hence I appreciate the role of electronic configuration of the atom .
