Explain that argon has 18 protons and 18 electrons. There are 2 electrons on the first energy level, 8 electrons on the second level, and 8 electrons on the third energy lev- el. Have students ...

Tim Radford is the author of The Consolations of Physics. He was science editor of The Guardian for 13 years. In The Periodic Table, Primo Levi — scientist, poet, writer — makes chemistry a ...

This could open up newer possibilities in making superheavy elements in the lab and understanding nuclear stability at higher ...

Meet nihonium (Nh), moscovium (Mc), tennessine (Ts) and oganesson (Og), the newest elements on the periodic table to receive names. But don’t get too attached to the nomenclature for these ...

Scientists announce a 'nuclear' periodic table Date: May 27, 2020 Source: Kyoto University Summary: Physicists develop a 'nuclear periodic table'. While the traditional table is based on the ...

The periodic table currently has 118 chemical elements (SN: 11/30/16).The five heaviest elements were all produced using a beam of calcium-48. That’s a variety, or isotope, of calcium with 28 ...

Imagine the periodic table as a playground of bullies, snobs and wallflowers, and you might memorize the elements overnight. Chemistry, after all, is about making and breaking bonds. It's about ...

Most elements on the periodic table have at least one stable form. But some don’t. Here’s how long those unstable members endure.

To create 117, with the temporary periodic table placeholder name ununseptium, the researchers smashed calcium nuclei (with 20 protons apiece) into a target of berkelium (97 protons per atom).

His team found that an isotope of plutonium, Pu-239, could be split, releasing an enormous amount of destructive energy. The Fat Man bomb, dropped on Nagasaki in 1945, had a plutonium core. Glenn ...
