Well-known to scientists, a working tool for chemists, the periodic table has been given a new look on the initiative of the European Chemical Society. The purpose of this revised painting? Keep an eye on the state of the planet’s resources in the face of an increasingly greedy production of rare elements.
thatby Mendeleev is a great class classic. This table contains classified according to their and organized according to their electronic configuration.
Due to the information it contains, it is primarily intended for chemists. However, this table was recently revisited by the European Society of Chemistry, interested in the elements that make up matter (atoms, ions, etc.), their properties and the chemical bonds that can be made between… image=”https://cdn.futura-sciences.com/buildsv6/images/midioriginal/1/d/2/1d2ee349de_91893_chimie-def.jpg” data-url=”https://news.google.com/ sciences/ Definitions/Chemie-Chemie-15837/” data-more=”Read more”>who have given it a new function: to inform professionals but also the general public about the evolution of the availability of various such as copper (Cu) and the copper ion…” data-image=” https:/ /cdn.futura- sciences.com/buildsv6/images/midioriginal/7/4/d/74d6f5bda2_92001_element-chimie.jpg” data-url=”https://news.google.com/sciences/definitions/chimie -element- chemical-15852/” data-more=”Read more”> on their use and on the geopolitical issues that are sometimes addressed.
Because if theFor example, when a source summarizes all chemical elements present, it does not represent the natural abundance of each of those elements. A key point for understanding certain current problems.
Natural resources are not infinite
The new version of the periodic table of the European Chemical Society therefore shows this abundance by assigning different sizes to the previously uniform squares. A code is sometimes added, the color…” data-image=”https://cdn.futura-sciences.com/buildsv6/images/midioriginal/7/9/5/7951943cc1_85596_couleur.jpg” data-url=” https://news.google.com/science/definitions/physics-color-4126/” data-more=”Read more”>

It is imperative to recognize this.

The periodic table thus raises a question of ethics and .
Consider the issue of availability from an ethical perspective
In this way, the elements that are the subject of geopolitical issues or even responsible for armed conflicts are highlighted.
The wavelengths of visible light range from about 380 nm (violet) to 780 nm (red). The visible spectrum is…” data-image=”https://cdn.futura-sciences.com/buildsv6/images/midioriginal/b/6/9/b697a0c09f_85912_lumiere.jpg” data-url=”https:// news.google.com/science/definitions/physics-light-326/” data-more=”Read more”> in this new periodic table, which is further developed and revised every year. Therefore, between 2019 and 2021, the European Chemical Society reviewed the color of the General Box

This modification follows a reflection on the the carbon resource. Because even if carbon is currently available everywhere, the reserves are sufficient Fossil fuels are in danger of running out if our energy practices are not changed. In addition, these reserves are often the origin of conflicts or are used to finance conflicts, as shown by the war in Ukraine with the question of importing Russian gas.
The goal of this revised periodic table is to draw attention to the limitations of our planet to provide us with what we need or think we need. It also encourages chemists and engineers to think about their practices. The limitation of planetary resources must be taken into account at all levels and new solutions such as e.gintensive, should be taken into account and urgently encouraged.
