AbstractThe Periodic Table is the most representative icon of chemistry, because it contains all the chemical elements currently known, which constitute the true bricks of the universe. In 1869 the Russian chemist Dimitri Mendeleyev published his first periodic table, placing in order the 63 elements known at the time. On 28 November 2016 IUPAC announced the official names and the symbols of four elements, defining the current Periodic Table with 118 elements.

The change from the traditional Western and Chinese view of the elements involving materials such as water, air, earth, wood, metal and fire, to the chemical elements making up the periodic table, to atoms, to particles such as protons, neutrons and electrons, and then to quarks was inevitable. The order of discovery of these ideas of the ultimate constituents of matter was necessary, in that they could not have been discovered in any other order. This was because nature has a particular structure and we have a particular place in nature. The traditional view of the elements could be obtained by naked eye observation, and the view of nature as being made up of the chemical elements in the periodic table was next discovered, as it involved the decomposition of traditional elements, such as air and water. This led to the idea there was a separate atom for each element which explained the differences between the elements. The sub atomic particles were discovered in a necessary order with the outer particles like the electron being discovered earlier, and inner particles such as quarks being discovered later. The order of discovery of particles was also affected by the properties of the particles. The charges of particles, their mass and ability to survive outside the particles they make up, and other properties will make a particle harder or easier to discover. The order of discovery is inevitable and set by the structure of the universe. The structure of the universe includes the structure of the atom, and of the particles making up the atom, and the properties of the atom, and of the particles making up the atom.

Abstract The Periodic Table of Chemical Elements has without any doubt developed to one of the most significant achievements in natural sciences. The Table (or System, as called in some languages) is capturing the essence, not only of chemistry, but also of other science areas, like physics, geology, astronomy and biology. The Periodic Table is to be seen as a very special and unique tool, which allows chemists and other scientists to predict the appearance and properties of matter on earth and even in other parts of our the universe.

The first elements of the Periodic Table – hydrogen, helium and partly lithium - appeared in the first seconds after the birth of the Universe. The first stars “gathered” from these materials are the natural factories of the synthesis of heavier elements, not only throughout their lives, but even during their death process, during Supernova explosions. Supernova explosions, in their turn, are powerful factories for the production of heavy elements. Modern instruments allow scientists not only to register such events, but also to determine how many different chemical elements were formed during such events. The recent discovery of the merging neutron stars and subsequent studies of their afterglow allowed us to clarify the process of formation of superheavy elements in the Universe up to the gold and uranium. Thus, astrophysical observations give scientists the most important information about the “production rates” of elements in the nature, and their abundance in the Universe.

AbstractIn 2019, the world celebrated the International Year of the Periodic Table of Chemical Elements (IYPT2019) and the IUPAC centenary. This happy coincidence offered a unique opportunity to reflect on the value and work that is carried out by IUPAC in a range of activities, including chemistry awareness, appreciation, and education. Although IUPAC curates the Periodic Table and oversees regular additions and changes, this icon of science belongs to the world. With this in mind, we wanted to create an opportunity for students and the general public to participate in this global celebration. The objective was to create an online global competition centered on the Periodic Table and IUPAC to raise awareness of the importance of chemistry in our daily lives, the richness of the chemical elements, and the key role of IUPAC in promoting chemistry worldwide. The Periodic Table Challenge was the result of this effort.

AbstractThis year (2009) marks the 140th Anniversary of Mendeleev's original 1869 periodic table of the elements based on atomic weights. It also marks the 175th anniversary of his birth in Tolbosk, Siberia. The history of the development of periodic tables of the chemical elements is briefly reviewed beginning with the presentation by Dmitri Mendeleev and his associate Nikolai Menshutkin of their original 1869 table based on atomic weights. The value, as well as the sometimes negative effects, of periodic tables in guiding the discovery of new elements based on their predicted chemical properties is assessed. It is noteworthy that the element with Z=101 (mendelevium) was identified in 1955 using chemical techniques. The discoverers proposed the name mendelevium to honor the predictive power of the Mendeleev Periodic Table. Mendelevium still remains the heaviest element to have been identified first by chemical rather than nuclear or physical techniques. The question concerning whether there will be a future role for the current form of the periodic table in predicting chemical properties and aid in the identification of elements beyond those currently known is considered.

TheLiber de orbe, attributed to Māshā'allāh (fl. 762–ca. 815) in the list of Gerard of Cremona's translations, stands out as one of the few identifiable sources for the indirect knowledge of Peripatetic physics and cosmology at the very time Aristotle's works on natural philosophy themselves were translated into Latin, from the 1130s onward. This physics is expounded in an opening series of chapters on the bodily constitution of the universe, while the central section of the treatise covers astronomical subjects, and the remaining parts deal with meteorology and the vegetal realm. Assuming that Gerard of Cremona's translation of theLiber de orbecorresponds to the twenty-seven chapter version that circulated especially during the thirteenth and fourteenth centuries, it was, however, not this version, but a forty-chapter expansion thereof that became influential as early as the 1140s. It may have originated in Spain, as indicated, among others, by a reference to the difference of visibility of a lunar eclipse between Spain and Mecca. Unlike the twenty-seven chapterLiber de orbe, this expanded and also partly modified text remains in manuscript, and none of the three copies known so far gives a title or mentions Māshā'allāh as an author. Instead, the thirteenth-century witness that is now in New York attributes the work to an Alcantarus:Explicit liber Alcantari Caldeorum philosophi. While no Arabic original of the twenty-seven chapterLiber de orbehas come to light yet, Taro Mimura of the University of Manchester recently identified a manuscript that partly corresponds to the forty-chapter Latin text, as well as a shorter version thereof.

Bahasa di dunia sangat beragam, tetapi dimungkinkan adanya persamaan. Sebagai pelajar, sangat penting untuk mempelajari fonologi dan fonetik dari berbagai  bahasa untuk membandingkan dan menyamakan satu dengan yang lainnya. Bahasa Inggris dan Arab sama-sama memiliki struktur linguistik terbesar dari semua bahasa di dunia. Kedua bahasa tersebut memiliki kesamaan ciri, seperti konsonannya. Dari persamaan tersebut, Lestiono dan Gusdian (2017) melakukan penelitian terhadap konsonan bahasa Arab dalam membantu pengucapan bahasa Inggris, yang dikenal sebagai tabel kosonan bahasa Inggris-Hijaiyah. Tujuan dari penelitian ini adalah untuk mengetahui pengucapan dari delapan anggota paduan suara universitas dalam menyanyikan lagu-lagu bahasa Inggris sebelum dan sesudah pengenalan konsonan Hijaiyah sebagai mediasi. Dalam penelitian ini digunakan studi kasus, yang termasuk dalam desain kualitatif yang digunakan dalam mencapai pengucapan yang dibangun oleh subjek penelitian melalui observasi, analisis, dan deskripsi. Objek penelitian ini adalah bunyi konsonan yang dihasilkan oleh peserta penelitian saat menyanyikan lagu “When I Sing” oleh Russel Robinson dan Charolette Lee dan “The Seal Lullaby” oleh Eric Whitacre dan Rudyard Kipling. Instrumen yang digunakan adalah dokumen analisis. Dalam analisis ditemukan adanya partisipan yang salah dalam mengucapkan kosa kata yang ditargetkan sebelum diperkenalkan dengan konsonan Hijaiyah. Setelah pengenalan konsonan Hijaiyah sebagian besar peserta terdengar akurat. Hal ini dapat disimpulkan bahwa konsonan Hijaiyah dapat memfasilitasi anggota paduan suara mahasiswa untuk belajar dan menghasilkan kata-kata bahasa Inggris yang akurat saat bernyanyi.    Language in the universe is various; however, it does not close the possibility that each languages have an equation. As a learner, it is crucial to learn the phonology and phonetics of some languages to compare and equalize one another. English and Arabic both have the biggest linguistic construction. Both languages have the sameness of characteristics such as some of their consonants. From those similarities, Lestiono and Gusdian (2017) conducted a study on Arabic Consonant sounds to arrive at English Pronunciation, known as English-Hijaiyah consonant corresponding chart. The objective of the current research is to discover the pronunciation of eight university choir members in singing English songs before and after the introduction of Hijaiyah consonants as the mediation. In this present study acquire a case study, which is included to qualitative design that was used in arriving at the pronunciation constructed by the research subjects through observation, analyzation, and description.. The research objects were the consonant sounds produced by research participants while singing “When I sing” by Russel Robinson and Charolette Lee and 'The Seal Lullaby” by Eric Whitacre and Rudyard Kipling. The instrument was document analysis. In the findings, participants mispronounced  many of the targetted words before they were introduced to Hijaiyah consonants as the mediation . Whereas, the pronunciation after the introduction showed that most of the participants sounded correct. This can be concluded that Hijaiyah consonants can facilitate the university student choir members to learn and produce accurate English words while singing.

The article discusses a new approach to the formation of periods of the Periodic Table of Mendeleev. With the help of the new formula and the first proposed quantum states of the outer electron shells of atoms of chemical elements, the periods of the periodic table are reformatted. It is supposed to reduce the number of periods in the table by introducing the corresponding sub-periods. This is confirmed by the material given in the article. The following description of the order of formation of electron layers is proposed: the principal quantum number (n), then the newly proposed quantum states of electrons («first» and «second»), which in turn constitute the electronic configurations of sub-periods in periods, and only then the remaining quantum orbitals (s, p, d and f).
