To expand the periodic table, it might be time to go titanium. A new study lays the groundwork to expand the periodic table with a search for element 120, to be made by slamming electrically charged ...

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 ...

At the far end of the periodic table is a realm where nothing is quite as it should be. The elements here, starting at atomic number 104 (rutherfordium), have never been found in nature. In fact, they ...

Why does changing just one proton in the nucleus of an atom create a different element? The number of protons in an atomic nucleus determines the number of electrons needed for a neutral atom, ...

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 ...

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 ...

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 ...

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 ...
