Dobereiner arranged the elements in the order of increasing atomic masses in a triad. The arrangement was modified by John Newlands and later by Dimitri Meneleev. Even Mendeleev's arrangement was later modified by Henry Moseley resulting in the Modern Periodic Table. There anre many other similar example in the history of scientific advancement where theoric and novels were modified by later scientists and the origin contributors accepted these modification happily.
Answer the following questions based on the above information:
(i) How does the Modern Periodic Law given by Moseley different from Periodic Law stated
by Mendelleev?
(ii) What scientific values can be associated with the above ancedotes?
(iii) Give an example from your life experiences so far that reflects display of such values by you.
