When two hydrogen atoms get close enough, the electron from each atom feels an attraction from the proton in the other atom's nucleus. This attraction pulls the atoms together. The electrons end up ...

Researchers have directly visualized a rare type of chemical bond between some of the heaviest elements in the periodic table, providing experimental evidence of how these atoms share electrons in ...

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, ...

Atomic-scale imaging emerged in the mid-1950s and has been advancing rapidly ever since—so much so, that back in 2008, physicists successfully used an electron microscope to image a single hydrogen ...

In an experiment akin to stop-motion photography, scientists have isolated the energetic movement of an electron while "freezing" the motion of the much larger atom it orbits in a sample of liquid ...

Researchers have experimentally caused electrons to bend in bilayer graphene with the use of light. The way electrons flow in materials determine its electronic properties. For example, when a voltage ...

In ancient Greece, most people thought that matter was made up of combinations of four elements: earth, air, fire and water. There were a small number of Greeks who had a different idea. They believed ...

For the first time, researchers have pushed electrons to flow so fast they went supersonic, creating a shockwave. The currents of electricity flowing through our devices share a name with river ...
