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 ...

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 ...

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 ...

He was the first person to recognise the periodic trends in the properties of elements, and the graph shows the pattern he saw in the atomic volume of an element plotted against its atomic weight. A ...

An international team led by scientists of GSI/FAIR in Darmstadt, Johannes Gutenberg University Mainz and the Helmholtz ...

the atomic weights of which should be comprehended between 65 and 75; he had even gone so far as to describe in detail the properties of the three hypothetical elements—ekaboron, eka-aluminum ...

In recent decades, researchers have pushed the boundaries of the periodic table, synthesizing the heaviest elements known to ...

Where does the periodic table of chemical elements end and which processes lead to the existence of heavy elements? Researchers report on experiments to come closer to an answer. They gained insight ...
