2 What is The Periodic Table? The Periodic Table is a table that contains all the chemical elements organized on the basis of their atomic number (number of protons in the nucleus). The standard form of the table consists of a grid of elements laid out in 18 columns and 7 rows, with a double row of elements below that.

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.
