Interactive 3D Periodic Table of the 118 Elements

An interactive periodic table you can explore in 3D

Elementum 3D is a free periodic table of all 118 confirmed chemical elements. Browse the classic table, or rearrange the same elements as a sphere, helix or set of rings. Search by name, symbol or atomic number, filter by category, block or stability, and open any element to see its atomic mass, group, period and electron shells beside an orbiting Bohr model.

Who it is for

Students and learners: see how groups, periods and electron shells explain chemical behaviour, and use the colour modes to revise categories and blocks.
Teachers: project the table, switch layouts and open the Bohr model to show how shells fill across a period.
Enthusiasts: wander through the elements and read a short overview of each one's uses.
Researchers: use the data table below as a quick reference, and cite IUPAC publications for formal work.

How to use it

Tap or click a card to open the element. Use the arrow buttons or the left and right arrow keys to move to the next one.
Drag to move the table, scroll or press + and − to zoom, and press 0 to reset the view.
Press G, S, H or R for the table, sphere, helix or rings layout, and press / to focus search.
Move the pointer across the table and the cards rise toward you. Click empty space to jiggle them, press B to scatter them, and press P to play a find-the-element game. In the Bohr model, tap the atom to excite its electrons.
Every element has a shareable link, for example #Fe for iron.

Reading an element card

The number at the top left is the atomic number. The large letters are the element symbol, followed by the name and the standard atomic mass in unified atomic mass units. The number at the top right is the group; f-block elements show f instead. The card colour follows the colour mode you pick: category, s/p/d/f block, or whether the element has a stable isotope.

Periodic table FAQ

How many elements are in the periodic table?

The periodic table has 118 confirmed elements, numbered 1 (hydrogen) to 118 (oganesson). Elements 1 to 94 occur naturally on Earth, at least in trace amounts, while elements 95 to 118 have only been made artificially in laboratories.

What is the atomic number of an element?

The atomic number is the number of protons in an atom's nucleus. It defines the element: every atom with 6 protons is carbon, and in a neutral atom the atomic number also equals the number of electrons.

What is the difference between a group and a period?

Groups are the 18 vertical columns, and elements in the same group tend to behave alike because their outer electrons are arranged similarly. Periods are the 7 horizontal rows. A period number usually matches the number of occupied electron shells; palladium is the well-known exception.

Why are some atomic masses shown in square brackets?

Elements with no stable isotopes have no single natural average mass. For these, the bracketed value is the mass number of the isotope with the longest known half-life, for example [98] for technetium.

What do the electron shells on each element mean?

They list how many electrons sit in each shell, labelled K, L, M, N, O, P and Q from the nucleus outward. This is a simplified Bohr-style picture. Modern chemistry describes electrons in orbitals, but shell counts still show why elements in a group behave alike.

Which elements are liquid at room temperature?

Only two elements are liquid at standard room temperature and pressure: mercury, a metal, and bromine, a nonmetal. Gallium and caesium melt only slightly above room temperature.

What are the lanthanides and actinides?

They are two rows of f-block elements, atomic numbers 57 to 71 and 89 to 103, usually drawn beneath the main table to keep it compact. In Elementum 3D they sit in their own rows below the main grid.

About the data

Atomic masses follow the abridged standard atomic weights published by IUPAC. A bracketed value is the mass number of the longest-lived known isotope. Electron shells show ground-state arrangements by principal shell. Lanthanides (La to Lu) and actinides (Ac to Lr) are grouped in the f-block following common convention, although the placement of lutetium and lawrencium is still discussed. The "no stable isotope" flag applies to technetium, promethium and every element from polonium (84) upward.
