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 ...

Atoms are the building blocks of matter. Everything around us — from air and water, to rocks, plants and animals — as well as everything within our bodies, is made up of atoms. They are very small, ...

The word magic is not often used in the context of science. But in the early 1930s, scientists discovered that some atomic nuclei—the center part of atoms, which make up all matter—were more stable ...

From nearly indestructible metals, like tungsten, to delicate clouds in the sky, atoms make up everything around us. But do these atoms ever touch each other? As with most topics in atomic physics, ...

As though it wasn’t hard enough to memorize the names and atomic weights of 117 elements in the periodic table, scientists have now confirmed a new one. Researchers from Lund University in Sweden ...

Everything we can see and touch, and quite a lot that we can’t as well, is made of tiny particles called atoms. Some substances, like particles of this iron, contain only one kind of atom. Iron is an ...

Since the beginning of time, human beings have sought to understand what the universe and everything within it is made up of. And while ancient magi and philosophers conceived of a world composed of ...

The chemical identity of individual atoms on a surface can now be determined using an incredibly powerful atomic force microscope. It means that scientists can now look at a mixed material and pick ...
