What are the 118 elements modern periodic table?
Conclusion – Out of all the 118 Elements, 98 Elements are found in nature (those with atomic number 1- Hydrogen ‘H’ to atomic number 98 – Californium ‘Cf’; in the periodic table), with the rest being synthesized from the naturally occurring elements, in a laboratory.
- Elements synthesized in the laboratory include Einsteinium (99), Fermium (99) and Nobelium (102).
- However, this figure can change with time and better understanding, as some elements found after radioactive decay after nuclear testing experiments, therefore considered initially to be man-made, have subsequently been found in nature albeit in trace quantities.
Also, out of the many elements occurring in nature not all of them occur in pure or native form. like Helium, Argon, Neon, etc., are a few elements occurring in pure form. Metals like Gold, Silver, Copper, occur in their native form. Non-metals like carbon, nitrogen and oxygen occur in native form.

: Periodic Table of the Elements
Is the periodic table Russian?
Dmitri Mendeleev came up with a predictive version of the periodic table of elements Ria Novosti/Science Photo Library On 17 February 1869, Russian chemist Dmitri Mendeleev jotted down the symbols for the chemical elements, putting them in order according to their atomic weights and inventing the periodic table,
He wrote down the sequence in such a way that they ended up grouped on the page according to known regularities or ‘periodicities’ of behaviour. It was perhaps the greatest breakthrough in the history of chemistry. Mendeleev’s ideas, which built on the earlier work of French chemist Antoine Lavoisier in the previous century, totally changed the way chemists viewed their discipline.
Now each chemical element had its number and fixed position in the table, and from this it became possible to predict its behaviour: how it would react with other elements, what kind of compounds it would form, and what sort of physical properties it would have.
- Soon, Mendeleev was predicting the properties of three elements – gallium, scandium and germanium – that had not then been discovered.
- So convinced was he of the soundness of his periodic law that he left gaps for these elements in his table.
- Within twenty years, all three had been found, and their properties confirmed his predictions almost exactly.
Mendeleev himself was surprised by how fast his ideas were confirmed. In a prestigious Faraday Lecture to the Royal Institution in London in 1889, he admitted that he had not expected to live long enough ‘to mention their discovery to the Chemical Society of Great Britain as a confirmation of the exactitude and generality of the periodic law’.
As news of his remarkable accomplishment began to spread, Mendeleev became something of a hero, and interest in the periodic table soared. In all, Mendeleev predicted 10 new elements, of which all but two turned out to exist. He later proposed that the positions of some pairs of adjacent elements be reversed to make their properties fit into the periodic pattern.
He suggested swapping cobalt with nickel and argon with potassium, which he believed had been wrongly placed because their true atomic weights were different from the values chemists had determined. It took until 1913, some six years after Mendeleev had died, to clear up this ambiguity.

Tennessine is a synthetic chemical element with the symbol Ts and atomic number 117. It is the second-heaviest known element and the penultimate element of the 7th period of the periodic table, The discovery of tennessine was officially announced in Dubna, Russia, by a Russian–American collaboration in April 2010, which makes it the most recently discovered element as of 2023.
One of its daughter isotopes was created directly in 2011, partially confirming the results of the experiment. The experiment itself was repeated successfully by the same collaboration in 2012 and by a joint German–American team in May 2014. In December 2015, the Joint Working Party of the International Union of Pure and Applied Chemistry (IUPAC) and the International Union of Pure and Applied Physics (IUPAP), which evaluates claims of discovery of new elements, recognized the element and assigned the priority to the Russian–American team.
In June 2016, the IUPAC published a declaration stating that the discoverers had suggested the name tennessine after Tennessee, United States, a name which was officially adopted in November 2016. Tennessine may be located in the ” island of stability “, a concept that explains why some superheavy elements are more stable compared to an overall trend of decreasing stability for elements beyond bismuth on the periodic table.
- The synthesized tennessine atoms have lasted tens and hundreds of milliseconds,
- In the periodic table, tennessine is expected to be a member of group 17, the halogens,
- Some of its properties may differ significantly from those of the lighter halogens due to relativistic effects,
- As a result, tennessine is expected to be a volatile metal that neither forms anions nor achieves high oxidation states,
A few key properties, such as its melting and boiling points and its first ionization energy, are nevertheless expected to follow the periodic trends of the halogens.
Does Bill Gates have a periodic table?
Bill Gates has a wall-sized installation of the periodic table with a sample of each element in its own glass-fronted case. – Science and technology have always fascinated Bill Gates. But did you know the Microsoft founder had a giant periodic table mounted on the wall of his office? Yes, Gates has a wall-sized installation of the periodic table with a sample of each element in its own glass-fronted case.
- Several photos of the incredible periodic table have surfaced online over the years which show a lighted vitrine dedicated to every chemical which serves as an actual representation of the same.
- A recent tweet by Amazing Astronomers showed the image of Gates’ periodic table that’s reportedly installed in his private office outside Seattle.
This amazed the chemistry enthusiasts and others on the internet as they started reacting and raising questions about the interesting ‘office’ phenomenon. “Ok, that’s so freaking cool. Gosh damn. Right on,” read a comment on Twitter. Meanwhile, other users inquired about the storage of radioactive elements such as francium, uranium, etc.
Apart from francium I’m assuming,” commented one while the other one said, “Kinda wondering how they house the radioactive stuff lol”. “It is not possible to physically have all the elements of the periodic table,” mentioned the third user. One of them also warned, “you shouldn’t do this because some of the elements are unstable and could mix with the others and well some of them are highly radioactive you shouldn’t do this because some of the elements are unstable and could mix with the others and well some of them are highly radioactive.” Apart from francium I’m assuming.— Youssof Altoukhi (@Youssofal_) January 31, 2023 Kinda wondering how they house the radioactive stuff lol— BillyBitcoins @781 (@BillyBitcoins) January 31, 2023 It is not possible to physically have all the elements of the periodic table— Frank (@Frankvuelvex) January 31, 2023 In 2019, Will Smith also visited Gates’ office after watching his Netflix documentary ‘Inside Bill’s Brain: Decoding Bill Gates’.
Posting an Instagram video about his visit to the Seattle office, Smith remarked, “His office is ridiculous”. But what stunned him was not the breathtaking view or the library, but the massive periodic table which took up the entire wall of his office (except the radioactive chemicals).
Is element 0 real?
Neutronium is the hypothetical element zero, with no protons in its atomic nucleus. Neutronium is the name of a theoretical element with atomic number 0 and symbol Nu that consists entirely of neutrons.
Has element 123 been discovered?
Unbitrium ( pronounced /ənˈbɪtriəm/ ) is the temporary name of an undiscovered chemical element in the periodic table that has the temporary symbol Ubt and has the atomic number 123.
Does element 114 exist?
Flerovium is a superheavy chemical element with symbol Fl and atomic number 114.
Why are there no more elements after 118?
History – Heavier elements beyond the actinides were first proposed to exist as early as 1895, when the Danish chemist Hans Peter Jørgen Julius Thomsen predicted that thorium and uranium formed part of a 32-element period which would end at a chemically inactive element with atomic weight 292 (not far from the 294 known today for the first and only discovered isotope of oganesson ).
In 1913, the Swedish physicist Johannes Rydberg similarly predicted that the next noble gas after radon would have atomic number 118, and purely formally derived even heavier congeners of radon at Z = 168, 218, 290, 362, and 460, exactly where the Aufbau principle would predict them to be. Niels Bohr predicted in 1922 the electronic structure of this next noble gas at Z = 118, and suggested that the reason why elements beyond uranium were not seen in nature was because they were too unstable.
The German physicist and engineer Richard Swinne published a review paper in 1926 containing predictions on the transuranic elements (he may have coined the term) in which he anticipated modern predictions of an island of stability : he first hypothesised in 1914 that half-lives should not decrease strictly with atomic number, but suggested instead that there might be some longer-lived elements at Z = 98–102 and Z = 108–110, and speculated that such elements might exist in the Earth’s core, in iron meteorites, or in the ice caps of Greenland where they had been locked up from their supposed cosmic origin.
By 1955, these elements were called superheavy elements. The first predictions on properties of undiscovered superheavy elements were made in 1957, when the concept of nuclear shells was first explored and an island of stability was theorised to exist around element 126. In 1967, more rigorous calculations were performed, and the island of stability was theorised to be centered at the then-undiscovered flerovium (element 114); this and other subsequent studies motivated many researchers to search for superheavy elements in nature or attempt to synthesize them at accelerators.
Many searches for superheavy elements were conducted in the 1970s, all with negative results. As of April 2022, synthesis has been attempted for every element up to and including unbiseptium ( Z = 127), except unbitrium ( Z = 123), with the heaviest successfully synthesized element being oganesson in 2002 and the most recent discovery being that of tennessine in 2010.
As some superheavy elements were predicted to lie beyond the seven-period periodic table, an additional eighth period containing these elements was first proposed by Glenn T. Seaborg in 1969. This model continued the pattern in established elements and introduced a new g-block and superactinide series beginning at element 121, raising the number of elements in period 8 compared to known periods.
These early calculations failed to consider relativistic effects that break down periodic trends and render simple extrapolation impossible, however. In 1971, Fricke calculated the periodic table up to Z = 172, and discovered that some elements indeed had different properties that break the established pattern, and a 2010 calculation by Pekka Pyykkö also noted that several elements might behave differently than expected.
