Martian Periodic Table
Introduction
The periodic table is one of the most useful tools used by chemists. The properties were
found to vary periodically. The first periodic table was arranged by Dmitri Mendeleev
according to atomic mass in such a way that elements with similar properties were
grouped together. Henry Moseley later arranged the periodic table according to the
increasing atomic number. On a periodic table, the vertical columns are called families or
groups and can be named by the first element in that column (ex. Group 15: Nitrogen
Family). The horizontal rows are called periods and are numbered from top to bottom.
The periodic law is believed to be universal so that it should hold true not only on earth
but also throughout the universe, including the planet Mars.
