Periodic tableThe periodic table of the chemical elements is a tabular display of the known chemical elements. The elements are arranged by electron structure so that many chemical properties vary regularly across the table. Each element is listed by its atomic number	Periodic table (alternate)The Alternate Table is a periodic table perpendicularly rotated counterclockwise, hence like in many writing systems, the lower groups are to the left and the number increases to the right. Due to the rotation and the incorporation of the lanthanides and	Periodic table (big)Group 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 I II III IV V VI VII VIII Period 1 hydrogen1H helium2He 2 lithium3Li beryllium4Be boron5B carbon6C nitrogen7N oxygen8O fluorine9F neon10Ne 3 sodium11Na magnesium12Mg aluminium13Al silicon14Si phosphorus15
Periodic table (huge)The Huge Table is a detailed periodic table that does not fit into most computer screens. However, with a small font size, or in landscape mode, this table can be printed on one normal-size sheet of paper.

Seaborg in 1969. It is a logical extension of the principles behind the standard periodic table to include as-yet-undiscoved chemical elements. All of the undiscovered elements are named by the IUPAC
