Can you name everything from Ac to Zr? Test your knowledge of the periodic table and see if you can top the leaderboard ...

often called the periodic table, organizes all discovered chemical elements in rows (called periods) and columns (called groups) according to increasing atomic number. Scientists use the periodic ...

Scientists at Berkeley Lab are using a new technique to create increasingly heavier elements, with the goal of reaching ...

Just four years before Mendeleev announced his periodic table, Newlands noticed that there were similarities between elements with atomic weights that differed by seven. He called this The Law of ...

Besides these seven elements, there are seventeen more whose atomic weights, as given in the following table, differ from the results of Prof. Clarke's coinpu- 1 Richards and Parker: Proceedings Am.

The search for new elements comes from the dream of finding a variant that is sufficiently stable to be long-lived and not ...

The way we arrange them is in the order of increasing atomic number ... Now, the table is called the periodic table because the elements with similar properties occur at regular intervals.

There are more than a million objects in the Solar System’s asteroid belt. NASA’s even visited a few of them, such as Bennu and, soon, Psyche. However, another asteroid named 33 Polyhymnia presents a ...

Scientists have found an alternative way to produce atoms of the superheavy element livermorium. The new method opens up the possibility of creating another element that could be the heaviest in the ...
