Special site of Dr. Elements’ Periodic Table

Welcome to the wonderful world of elements!
I'm Dr. Elements.

Human beings, like you and me, are made up of elements. So are animals, plants, buildings, vehicles, stars and every other object you can think of. Understanding elements means you can understand almost anything in this world.
This page contains the latest version of the Tokyo Electron Periodic Table of Elements, including all the new elements. You can order a poster to have at home or use the table below with a device to learn about the characters of each and every element.
So have fun the unique world of elements.

TEL's AR Periodic Table is a periodic table of elements with augmented reality (AR) features. It is available as a poster and on this page to enjoy.
A free dedicated smartphone app brings the AR Enhanced Periodic Table to life to make learning fun. With narration included, these animations enable a deeper level of understanding of the elements.
There are two versions of the periodic table, one in Japanese and one in English. Use the app to operate the AR camera that supports your version.

Using the app

Download the Tokyo Electron AR App (free of charge) or update it to the latest version. Once it starts up, enjoy the animated footage of the element cards.

Supported devices

OS: iOS 11.3 and up, or Android 7.0 and up
(Depending on the specifications, it may not run correctly on some smartphone models.)

Notes:

Users may incur data fees when downloading or using this app.
The app may not operate correctly if the internet connection is weak. Ensure a strong signal before use.
Element cards may not be detected if part of the card is covered.
Enjoy the app with the 2017 edition of TEL's Periodic Table of the Elements.

Viewing the AR Periodic Table from a computer screen

Scroll to the AR Periodic Table on this page and click an element card to enlarge it. Open the app, start the AR camera and hold it over the enlarged element card.

Different colors represent different groups of elements with similar properties.

Hydrogen Alkali metals Alkaline earth metals^*1 Rare earth elements Actinoids d-block elements^*2 Boron group Carbon group Pnictogens Chalcogens Halogens Noble gases Other^*3

*1. Beryllium and magnesium are sometimes excluded from this group.
*2. Scandium and yttrium in Group 3 are also d-block elements. However, on this table they have been colored as rare earth elements.
*3. The “state at room temperature” and “classifications for metal/non-metal/metalloid elements” for elements from fermium to oganesson (elements 100 - 118) are estimates (as of April 2017). While the chemical characteristics of tennessine are unknown, it has been color-coded as a halogen due to the original element being halogen format. Moreover, although the chemical characteristics of oganesson are unknown, it has been color-coded as a noble gas because the element name is in noble gas format.
*The chemical characteristics of each element are based on the IUPAC (International Union of Pure and Applied Chemistry) agreement.*Figures for atomic weight are based on the “2017 Table of Atomic Weights” edited by the Chemical Society of Japan.
*Due to language differences, the design of cards and animations for each element may also be different in English and Japanese versions.
*Uses and applications written in the description of each element are examples.
*Information on each element is taken from the 2017 edition of Tokyo Electron’s AR Periodic Table of Elements.
*Certain marks in the AR videos may differ from the print edition.
<AR video explanation> Iron: The amount of iron found in hijiki seaweed has been revised in the 2016 edition of “Standard Tables of Food Composition in Japan” published by the Ministry of Education, Culture, Sports, Science and Technology. Iridium: The International Prototype of the Kilogram had been used in the definition of mass until May 2019; however, the Planck constant of quantum mechanics is now being used instead.

All matter known to man is made up of atoms. Atoms are comprised of a nucleus, containing protons and neutrons, which is encircled by electrons. Elements are the generic names used to categorize atoms with different properties.

Each atom always has the same number of electrons and protons, with the number of the element being the number of electrons/protons in the atom. In other words, hydrogen (atomic number 1) has one electron and one proton, helium (atomic number 2) has two electrons and two protons, and so on. The periodic table is the method by which we order all these elements by their atomic number.

The periodic table enables the properties of every element to be understood at a glance, so it is used as an useful guideline in the fields of chemistry and physics.
