<span>Martian table is believed to be the most important tool used
by chemists. On this table, it was found out that the properties of the
elements differ. It was Dmitri Mendeleev
and Henry Moseley who arranged the first periodic table and later arranged in
another manner, respectively. Dmitri arranged the elements according to the
