A modern version of the periodic table is constructed by Valery Tsimmerman, named the ADOMAH periodic table (2006). Its structure is based on the four quantum numbers of the electron configuration, hence it has a four-dimensional base.

PT "orizuru" A4 paper for you

How to fold it from the paper.

PT "orizuru" paper crane

The orizuru (ori- "folded," tsuru "crane"), or paper crane, is a design considered the most classic of all Japanese origami.

Here is a Periodic Table "orizuru" paper crane. The 32 column PT divided into two on the upper left and right sides of the wings, and the 18 column PT divided into four on the lower surface of the wings.

Background color shows subcategory in the metal–metalloid–nonmetal trend:

Metal: Alkali metal, Alkaline earth metal, Lanthanide, Actinide, Transition metal, Post-transition metal, Metalloid, Nonmetal: Polyatomic nonmetal, Diatomic nonmetal, Noble gas and Unknown chemical properties.

It causes the thickness of the folded paper, thinner paper is better for origami. Print out the PT "orizuru" PDF according to A4 size paper.

There are many folding lines printed in light gray but each line may shift slightly from the actual folding line.

It is useful to use a ruler. If you have two rulers you can fold the paper more accurately. Fit a ruler to the folding line, put another ruler from the back side of the paper then fold it carefully and slowly. You should crease the line clearly with a ruler or your nail.

There are a lot of instructions of orizuru.

Here is an example:

On 28 November 2016, the International Union of Pure and Applied Chemistry (IUPAC) approved the name and symbols for four elements: nihonium (Nh), moscovium (Mc), tennessine (Ts), and oganesson (Og), respectively for element 113, 115, 117, and 118.
