Images of circular periodic tables of the elements

The periodic table is an arrangment of the chemical elements ordered by atomic number so that chemical periodic properties of the elements (chemical periodicity) are made clear.

There is no one single or best structure for the periodic table. Circular forms of the periodic table do not quite demonstrate strict atomic number ordering. Perhaps spiral forms do this better.

Image of a spiral periodic table — **Circular form of the periodic table.** Note that the standard form of the periodic table usually has hydrogen (H) located in Group 1 despite it being a gas while the other compounds are metals. The reason for this position for hydrogen is not chemical but electronic; hydrogen and all the Group 1 metals have the electronic configuration ns¹ (n is the principal quantum number). Here both hydrogen (H) and helium (He) are coloured blue. Although located with all the other p-block elements, their valence electronic configurations of 1s¹ and 1s² are exclusively s electrons.

Images of various periodic tables

There are many variants of the periodic table, some useful, others less so. A few are linked shown below. Click on the images below to see images of the periodic table in a variety of styles. Many other periodic table formats are catalogued at Mark Leach's Meta-synthesis web site. A classic book showing many forms of the periodic table in print is: Edward G. Mazurs, Periodic representations of the periodic system during one hundred years, University of Alabama Press USA, 2nd edition, 1974. ISBN: 0-8173-3200-6.

The standard form of the periodic table shown here includes periods (shown horizontally) and groups (shown vertically). The properties of elements in groups are similar in some respects to each other.
