Explain the merits of Moseley's long form of periodic table.

Explanation

Merits of Moseley 's long form of periodic table :
(i) As the classification is based on atomic number , it relates the position of an element to its electron configuration.
(ii) The position of zero group is also justified in the table as group 18.
(iii) The table completely separates metals and non metals.
(iv) The table completely separates two sub groups , lanthanides and actinides dissimilar elements do not fall together.
(v) The greatest advantage of this periodic table is that this can be divided into four blocks namely s.p.d and f- block elements.
(vi) This arrangement of elements is remember understand and reproduce.
