4. Extra Periodic Table Facts
The rows of the table are called periods and the columns are called groups. There are many periodic tables with structures other than that of the standard form. Within 100 years of the appearance of Mendeleev's table in 1869 it has been estimated that around 700 different periodic table versions were published.
