Theory suggests that if physicists could cram just the right amount of stuff into a nucleus, the resulting element would hit a sweet spot. It could romp on the island of stability for days, months or ...

For now, they're known by working names, like ununseptium and ununtrium — two of the four new chemical elements whose discovery has been officially verified. The elements with atomic numbers 113, 115, ...

A new super-heavy element, temporarily called 117, may soon be making its way into the periodic table after being successfully created in a laboratory setting. Made up of 117 protons, the element ...

We’ve reached the limit of a very successful way to make new elements in the lab. In new research, scientists unveil a new take on that technology and report its success. The heaviest elements could ...

The heaviest element that humans have ever found is called oganesson. Each atom of the stuff packs a whopping 118 protons into its dense center. In contrast, hydrogen—the most abundant element in the ...

Take a look around: Every single thing you see is made up of elements in the periodic table. Ever since scientists first cobbled together these catalogs of nature’s building blocks in the 19th century ...

Note: This video is designed to help the teacher better understand the lesson and is NOT intended to be shown to students. It includes observations and conclusions that students are meant to make on ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. The story of our cosmic history is one of an expanding and cooling ...

Biophysicists in Germany have discovered a diode for protons: just like the electronic component determines the direction of flow of electric current, the “proton diode” ensures that protons can only ...

The stuff of daily existence is made of atoms, and all those atoms are made of the same three things: electrons, protons and neutrons. Protons and neutrons are very similar particles in most respects.

Elements that do not exist in nature—that have been created in a laboratory—are unstable. After hours or days of one element bombarding another with enough energy for both to fuse, the resulting new ...
