The IUPAC Periodic Table Challenge now available in nine languages

On November 1, IUPAC has launched two additional translations of the Periodic Table (PT) Challenge: German and Romanian. The IUPAC PT Challenge dates back to the International Year of the […]

Time to review your Periodic Table

Following the reviews of atomic-weight determinations and other cognate data in 2015, 2017, 2019 and 2021, the IUPAC Commission on Isotopic Abundances and Atomic Weights (CIAAW) has released the “Standard Atomic Weights of the Elements 2021” (Pure and Applied Chemistry, 4 May 2022; https://doi.org/10.1515/pac-2019-0603)

IUPAC Periodic Table Challenge 2020: Top Schools Announced

Following the success of the IYPT2019*, in 2020 IUPAC continued the Periodic Table Challenge which not only had more questions but also welcomed more participants! Since its start in 2019, […]

IUPAC and ASRT launch the Arabic version of the periodic table challenge

IUPAC and the Egyptian Academy of Scientific Research and Technology (ASRT) have launched the Arabic version of the Periodic Table Challenge. The challenge is targeting young people and students around the world and an Arabic version of the challenge will extend participation from the MENA region.

IUPAC Periodic Table Challenge 2.0

IUPAC is now offering a new and expended Periodic Table Challenge and we invite everyone to play!

IUPAC Periodic Table of the Elements and Isotopes (IPTEI) for the Education Community

The IUPAC Periodic Table of the Elements and Isotopes (IPTEI) was created to familiarize students, teachers, and non-professionals with the existence and importance of isotopes of the chemical elements. The IPTEI is modeled on the familiar Periodic Table of the Chemical Elements. The IPTEI is intended to hang on the walls of chemistry laboratories and classrooms.

IUPAC100 Periodic Table of Younger Chemists half way

In celebration of IUPAC 100th anniversary of IUPAC and of the 2019 International Year of the Periodic Table, IUPAC and International Younger Chemists Network (IYCN) are creating a Periodic Table […]

Welcome to the International Year of the Periodic Table

There is no scientific symbol more ubiquitous than the periodic table. It is a map of our knowledge, particularly in chemistry, and a symbolic representation of the process of scientific research. It is also a reference tool that is much needed in scientific communication. This year, we are celebrating both science and communication through symbolic anniversaries: the 150 years of the periodic table as outlined by Dmitri Mendeleev in 1869, and the 100 years since the founding of the International Union of Pure and Applied Chemistry.

Chemical Speciation of Environmentally Significant Heavy Metals and Inorganic Ligands

The importance of considering chemical speciation (concentration of individual chemical entities) within a coherent framework is increasingly being recognised. Detailed understanding of the bioavailability and toxicity of heavy metals as well as their transport and sedimentation in natural aquifers requires knowledge of their speciation. The optimisation of many industrial processes, e.g. hydrometallurgy and pulp and[...]

Assessment of fundamental understanding of isotopic abundances and atomic weights of the chemical elements

During the 20th century, the CIAAW evaluated the atomic weights, isotopic abundances and their variations and made recommendations to a general chemical community. This project will evaluate a number of questions that have arisen, and these are posed below. In the 21st century, are there multiple audiences for the work of the CIAAW? Are Tables[...]

Development of an isotopic periodic table for the educational community

This project along with a follow-on project will develop, with the help of the Committee on Chemistry Education (CCE), learner oriented materials on an interactive periodic table that emphasizes the existence of isotopes and the role of isotopic compositions of elements on determination of atomic weights, and applications in sciences. In order to reach, and[...]

The Solubility of Beryllium Sulfate and Other Beryllium Compounds in Aqueous and Non-aqueous Media

Because of the large number of publications referring to beryllium sulfate, about one-half the total number to be compiled, beryllium sulfate evaluations and compilations will be listed first, followed by all other beryllium compounds listed according to the IUPAC Periodic Table. The volume could be of interest to scientists in industry and environmental science, due[...]

A Virtual Colloquium to Sustain and Celebrate IYC 2011 Initiatives in Global Chemical Education

This project evolved out of discussions of the 2011 CCE meeting in San Juan pertaining to the importance of sustaining IYC initiatives beyond 2011. Through email interactions during the Fall of 2011 the project took on its final shape with three distinct components. 1. Run the Spring 2012 ConfChem on IYC 2011 as a pre-conference[...]

Discovery of Elements with Atomic Numbers greater than 113

Early in 2012, the Presidents of IUPAC and IUPAP appointed a new Joint Working Party (the 4th) to consider claims for the discovery of new elements. The JWP has been charged with considering claims for the discovery of all the remaining elements in the seventh period for which no assignments have yet been made: namely[...]

Development and Global Dissemination of an IUPAC Interactive Electronic Isotopic Periodic Table and Supporting Resources for the Education Community

The IUPAC Periodic Table, hanging on the wall of classrooms around the world, found on the inside cover of most chemistry textbooks, and widely accessed on the web, has become an icon representing a core activity for IUPAC at the interface between fundamental scientific developments and educational outreach. Yet recent developments in what scientists know[...]

Accelerating Participation and Leadership of Women in Chemistry

Development of Vision and Strategy: One of the 4 objectives of the 2011 International Year of Chemistry was to celebrate the achievements of women in chemistry and honor Marie Curie. There were several main international activities on this theme. During the "Women Sharing a Chemical Moment in Time" networking event on January 18, 2011, women[...]

Assessment of fundamental understanding of isotopic abundances and atomic weights of the chemical elements (2016-2017)

The Commission on Isotopic Abundances and Atomic Weights evaluates the atomic weights, isotopic abundances and their variations and made recommendations to a general chemical community. This project will evaluate a number of questions that have arisen, and these are posed below. Review of the Commission's recent publications by the ICTNS (Interdivisional Committee on Terminology, Nomenclature[...]

The constitution of group 3 of the periodic table

The question of precisely which elements should be placed in group 3 of the periodic table has been debated from time to time with apparently no resolution up to this point. This question has also received a recent impetus from several science news articles following an article in Nature magazine in which the measurement of the[...]
