The Heritage Periodic Table Display: a comprehensive collection of the chemical elements that can fit in the hand. Embedded in acrylic are actual samples of 83 of the 118 elements- including pure bubbles of the gaseous elements- represented by 75 high purity samples and 7 compounds. 2019 marks the 150th anniversary of the world changing periodic system of Dmitri Mendeleev (published in 1869). This table and collection is the creative work of Tim and Cory Marriott of Engineered Labs Protoshop LLC
Many scientists worked on the problem of organizing the elements, but Dmitri Mendeleev published his first version of the periodic table in 1869, and is most often credited as its inventor. Since then, the periodic table has evolved to reflect over 150 years of scientific development and understanding in chemistry and physics. Today, with 118 known elements, it is widely regarded as one of the most significant achievements in science.
The official confirmation, granted by the International Union of Pure and Applied Chemistry (IUPAC), was years in the making, as these superheavy elements are highly unstable and tough to create. But scientists had strong reason to believe they existed, in part because the periodic table has been remarkably consistent so far. Efforts to conjure up elements 119 and 120, which would start a new row, are already underway.
French geologist Alexandre-Émile Béguyer de Chancourtois was the first person to recognize that elements could be grouped in recurring patterns. He displayed the elements known in 1862, ordered by their weights, as a spiral wrapped around a cylinder (see the illustration below). Elements vertically in line with each other on this cylinder had similar characteristics.
The Mendeleev periodic table easily accepted a brand new column for the noble gases, such as helium, which had eluded detection until the end of the 19th century because of their proclivity to not react with other elements.
More recent calculations have since overturned that limit. Feynman treated the nucleus as a single point. Allow it to be a ball of particles, and the elements can keep going until about 173. Then all hell breaks loose. Atoms beyond this limit may exist but only as strange creatures capable of summoning electrons from empty space.
Heavier, unstable elements may exist elsewhere in the universe, like inside dense neutron stars, but scientists can study them here only by smashing together lighter atoms to make heavier ones and then sifting through the decay chain.
Still, many scientists expect islands of stability to exist further down the road, where superheavy elements have relatively long-lived nuclei. Loading up certain superheavy atoms with lots of extra neutrons could confer stability by preventing the proton-rich nuclei from deforming. Element 114, for instance, is expected to have a magically stable number of neutrons at 184. Elements 120 and 126 have also been predicted to have the potential to be more durable.
But some claims of superheavy stability have already fallen apart. In the late 1960s chemist Edward Anders proposed that xenon in a meteorite that fell onto Mexican soil had come from the breakdown of a mystery element between 112 and 119 that would be stable enough to occur in nature. After spending years narrowing his search, he ultimately retracted his hypothesis in the 1980s.
One thing is for certain: Making each new element is going to get harder, not only because shorter-lived atoms are harder to detect, but because making superheavies may require beams of atoms that are themselves radioactive. Whether or not there is an end to the periodic table, there may be an end to our ability for creating new ones.

Some collectors attempt to collect very high purity samples of each element. Others prefer to find the element in everyday use. Some are averse to collecting the element as a compound or alloy, while others find this acceptable. Collectors may isolate elements in their own homes. Hydrogen, for example, can be easily isolated via the electrolysis of water.
In addition to the element samples, some element collectors also collect items connected with the element, such as manufactured goods containing the element, rocks and minerals with the element as a constituent or compounds of the element. Some manufacturers also sell coins made from pure elements, and density cubes made from the pure element can also be sourced on auction sites such as eBay.
Some commercial retailers now cater to the element collecting community, even selling large quantities in sets, since purchasing elements from large chemical companies is frequently prohibited or uneconomical for individuals. There are a number of specialist element providers which retail to the public over the web, sell individual element samples in addition to full and partial element sets. Many also sell elements through auction sites, such as eBay. Established specialist providers include Nova Elements, RGB Elements, Smart Elements, SMT Metalle Wimmer, PEGUYS, Metallium, Collect the Periodic Table, Luciteria, and Onyxmet.Element collecting presents many challenges: some elements, such as mercury, beryllium, thallium, plutonium, and arsenic are toxic and so are difficult to find or their sale is restricted. Others are extremely rare in commercial use, such as scandium, lutetium, and thulium, and are therefore hard to source or are comparatively expensive. Some, such as caesium, white phosphorus, and fluorine, are too reactive and have restrictions on their shipping; others, such as gallium, react corrosively and very fast with aluminium (e.g., as structural material in aircraft). Some, such as phosphorus and iodine, are controlled due to use in clandestine chemistry. Others, like radon and astatine, are radioactive and have half-lives too short for practical collection in addition to their radioactive hazards. Usually only the stable elements from hydrogen to bismuth (except the radioactive technetium and promethium) are collected, with the exceptions of the extremely long-lived thorium and uranium. It is possible to source other radioactive elements, such as radium (usually in the form of radium sulfate as part of luminescent paint on antique watch hands), americium (in the form of radioactive buttons containing 0.29 micrograms of americium extracted from older smoke detectors), promethium (often in the form of luminous paint in signal lights) and, technetium (which is sold by vendors, usually at very high prices).
Inspired by Samir Azer, a science teacher at the Kentucky School for the Blind, this set can assist in the instruction and demonstration of concepts related to the arrangement of the periodic table, atomic structure, ionic and covalent bonding, and balancing of chemical equations to students who benefit from a hands-on, interactive model. Special attention was given to make the materials tactually discriminable and visually appealing to the target population, yet appropriate for all students regardless of visual acuity.

The latest release of the Periodic Table (dated 4 May 2022) includes the most recent abridged standard atomic weight values released by the IUPAC Commission on Isotopic Abundances and Atomic Weights (CIAAW), compiled as part of the 2021 Table of Standard Atomic Weights 2021. For elements that lack isotopes with a characteristic isotopic abundance in natural terrestrial samples, the mass number of the nuclide with the longest confirmed half-life is listed between square brackets.

By virtue of its work in relation with the chemical elements, IUPAC can dispense a periodic table that is up-to-date. IUPAC involvement covers various aspects of the table and data that it unveils, and several reports and recommendations, some quite recent, attest of that input.
The table is yours to use. Details about the latest release are provided above. Details below provide multiple references to IUPAC journal in Pure and Applied Chemistry (PAC) and magazine Chemistry International (CI).
Claims for the discoveries of new elements appear time to time in the scientific literature. IUPAC, along with IUPAP, is involved in assessing these claims. In result, IUPAC technical reports are released that review each pertaining references and recognize the laboratory(ies) whose claims fulfill the agreed criteria.
When the discovery of a new element has been validated and the priority for its discovery has been assigned, the naming process can begin. The Laboratory to which the discovery has been assigned is invited to propose a name and symbol. IUPAC will then review the proposal, and if agreed, after an additional 5-month public review, will formalize the name. The most recent example of such recommendations were published in 2012 and for the names and symbols of the elements 114 and 116; See PAC 2012, Vol. 84, No. 7, pp. 1669-1672; -REC-11-12-03
The question of precisely which elements should be placed in group 3 has been debated from time to time. An IUPAC project has been recently initiated to resolve the question. Will group 3 consist of Sc, Y, Lu, and Lr or, will it consist of Sc, Y, La and Ac? 041b061a72
