We created our own Periodic Table of Elements, and we designed it to be the last table of elements you ever buy.
Existing tables become inaccurate every time a new element is discovered, and labs/scientists/classrooms around the world must buy updated tables. We thought this was ridiculous, so we made ours future-proof.
By adding blank boxes as placeholders for the predicted, undiscovered elements (according to the patterns created by the known elements), our table will never become obsolete.
When a new element is confirmed, write in its name, symbol, weight, and other properties in the appropriate box.
We also included the following info about the 118 known elements:
✅ Atomic weight (also indicated by the font weight)
✅ Font weight is also indicative of atomic weight
✅ Phase of matter at standard temperature & pressure
✅ Magnetic properties
✅ Synthetic or naturally-occurring
✅ Radioactivity indicator
✅ The longest half-life of radioactive elements
✅ Feynamium indicator
✅ Island of Stability information
✅ 172 elements (the placement of element 173 is unknown)
✅ Dimensions: 24" x 36"
✅ Neutral grey color-scheme to complement any room.
PLUS: For every periodic table purchased, we donate one to a classroom. We've donated scores so far.
The popular arrangement of the table of chemical elements was an extraordinary accomplishment by Dmitri Mendeleev. It neatly organizes atoms according to their number of protons, electron configuration, and various recurring properties. This ordering gives rise to important periodic trends of the elements such as atomic radius, reactivity, electronegativity and more. Using this arrangement and reading the trends within allows scientists to predict new elements and their properties.
There is some debate about how many different chemical elements can exist in our universe. At the time of printing, there are 118 confirmed elements, but as many as 173 are predicted. Rigorous tests are required to confirm the existence of a newly created or discovered element before it can be added to the table. When a new element is confirmed, the discoverer chooses a name and it is placed in the periodic table according to its properties.
THE PERIODIC TABLE
The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. The structure of the table shows periodic trends. The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right. The columns, called groups, contain elements with similar chemical behaviours. Six groups have accepted names as well as assigned numbers: for example, group 17 elements are the halogens; and group 18 are the noble gases. Also displayed are four simple rectangular areas or blocks associated with the filling of different atomic orbitals. The elements from atomic numbers 1 (hydrogen) through 118 (oganesson) have all been discovered or synthesized, completing seven full rows of the periodic table.
The first 94 elements, hydrogen through plutonium, all occur naturally, though some are found only in trace amounts and a few were discovered in nature only after having first been synthesized. Elements 95 to 118 have only been synthesized in laboratories, nuclear reactors, or nuclear explosions.The synthesis of elements having higher atomic numbers is currently being pursued: these elements would begin an eighth row, and theoretical work has been done to suggest possible candidates for this extension. Numerous synthetic radioisotopes of naturally occurring elements have also been produced in laboratories. The organization of the periodic table can be used to derive relationships between the various element properties, and also to predict chemical properties and behaviours of undiscovered or newly synthesized elements.
Russian chemist Dmitri Mendeleev published the first recognizable periodic table in 1869, developed mainly to illustrate periodic trends of the then-known elements. He also predicted some properties of unidentified elements that were expected to fill gaps within the table. Most of his forecasts soon proved to be correct, culminating with the discovery of gallium and germanium in 1875 and 1886 respectively, which corroborated his predictions. Mendeleev's idea has been slowly expanded and refined with the discovery or synthesis of further new elements and the development of new theoretical models to explain chemical behaviour.
The modern periodic table now provides a useful framework for analyzing chemical reactions, and continues to be widely used in chemistry, nuclear physics and other sciences. Some discussion remains ongoing regarding the placement and categorisation of specific elements, the future extension and limits of the table, and whether there is an optimal form of the table.
