PASSAGE - 1: In Mendeleeff's periodic table elements were classified on the basis of atomic weight & in modern periodic table on the atomic number. The lighter elements of 2 & 3 periods show similarities in their properties called diagonal relationship The atomic number of element separated from main body of periodic table is
