Developmental Principles

While still at school, most of us are deeply impressed by the underlying principles that so beautifully explain why the chemical elements are ordered as they are in the periodic table, and may wonder, with the theoretician Brian Goodwin, “whether there might be equally powerful principles that account for the awe-inspiring diversity of body forms in the living realm”. We have considered the arguments for developmental principles, conclude that they do exist and have specifically identified features that may generate principles associated with Hox patterning of the main body axis in bilaterian metazoa in general and in the vertebrates in particular. We wonder whether this exercise serves any purpose. The features we discuss were already known to us as parts of developmental mechanisms and defining developmental principles (how, and at which level?) adds no insight. We also see little profit in the proposal by Goodwin that there are principles outside the emerging genetic mechanisms that need to be taken into account. The emerging developmental genetic hierarchies already reveal a wealth of interesting phenomena, whatever we choose to call them.

Abstract As a follow-up to the 2019 International Year of the Periodic Table of Chemical Elements (IYPT2019), the Government of the Russian Federation proposed to establish and fund the joint UNESCO/Russian Federation International Prize for the Basic Sciences in the name of the Russian chemist Dmitry Mendeleev. The initiative is to provide further support to the UNESCO’s International Basic Sciences Programme (IBSP).

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.

Abstract The International Year of the Periodic Table of Chemical Elements 2019 (IYPT2019) has been celebrated during the year in over 130 countries, with well over a thousand events and festivities, reaching millions of young and old people, scientists and non-scientists. The event as a whole has been very successful; the 160-page report released last October illustrated in length the community partnership for global outreach and the diversity and success of the activities that took place throughout the year.

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.

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.

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).

In November 1868, the Ministry of Enlightenment of Russia approved the Charter of the Russian Chemical Society (RCS), one of the Founding Members of which had been Dmitri Mendeleev. The first report on Mendeleev Periodic Table of Chemical Elements was delivered during a meeting of the RCS in March 1869. Therefore 1869 is considered by the world science as the year of discovery of the Periodic Law and formulation of the Periodic Table of Chemical Elements. Year 2019 is the 150th anniversary since Dmitry Mendeleev discovered the Periodic System, and the United Nations proclaimed this year to be the International Year of the Periodic Table of Chemical Elements (IYPT2019). After a series of transformations, in 1992 the RCS became the Mendeleev Russian Chemical Society. In 2019, the RCS is holding anniversary events. The extraordinary Mendeleev Congress on General and Applied Chemistry is one of them. It will be held in Saint Petersburg in September 2019 and will host approximately 3,000 foreign and Russian participants. English-speaking symposia, conferences and round tables on current issues of strategic development of science and technology are planned as a part of the Congress.
