Group 1 elements react with moist air. They are stored in oil to stop air and water vapour coming into contact with them. Moist air reacts with potassium to form potassium oxide. This creates a ...

like atomic mass and chemical symbol. The periodic table’s arrangement also allows scientists to discern trends in element properties, including electronegativity, ionization energy, and atomic radius ...

The group 1 elements react quickly with oxygen in the air at room temperature. Most transition elements react slowly, or not at all, with oxygen at room temperature. Some transition metals react ...

The Periodic Table is a well-organized chart that contains all 118 known elements in the universe. These elements are the ...

Heavy ligands such as polyoxometalates are opening a new frontier in actinide chemistry. Studying materials that are both radioactive and rare presents significant challenges. The elements that follow ...

predicted the existence and properties of undiscovered elements that would fill the open spaces in his table. Learn more about the periodic table with this selection of educational resources from the ...

Chemical Properties. The chemical characteristics of the elements can equally well be studied, for there are the acid- and base-forming elements on the chart, whose zones gradually infiltrate from ...

A research team studied how iridium and palladium nanoparticles can change the properties of catalysts with minor degradation ...

For the first time, scientists have characterized a promethium coordination complex, advancing the understanding of ...

Promethium’s short half-life and lack of stable isotopes makes it difficult to study. In addition, promethium is difficult to ...
