An alternative periodic table of elements focusing on highly charged ions reveals new science that could support the quest ...

MIT researchers have created a periodic table that orders AI algorithms based on the properties they share with a ...

The periodic table’s arrangement also allows scientists to discern trends in element properties, including electronegativity, ionization energy, and atomic radius. Many scientists worked on the ...

Mrs Roberts: Well, elements that have similar properties to each other are put into vertical columns called groups. Now, the table is called the periodic table because the elements with similar ...

In this activity, students will use the online periodic table, ptable.com, to investigate a number of chemistry concepts. Students will use this online resource to explore information about the ...

Atomic numbers were not yet known, but the atomic weights worked well enough for ordering most of the elements, and Mendeleev was able to accurately predict the properties of missing elements. John ...

Scientists have discovered the elusive properties hidden within promethium, a rare earth element that has remained largely ...

Group 7 of the periodic table is something of an oddity. When the first periodic table was formulated by Mendeleev, it was the only group that contained just a single known element — manganese ...

It was debated whether the 'inert' monoatomic gases belonged to the periodic table owing to their lack of 'chemical properties'; elements coming late to the party, with no unpaired electrons to ...
