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 ...

The formula H₂O shows that water is made from two atoms of hydrogen (H) bonded to one atom of oxygen (O). Katie: Time for some science. And today it's a chemistry classic, the periodic table. And here ...

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 ...

Diatomic elements hate to be alone — so much so that they just aren't found as single atoms. Instead, they're always two atoms of the same pure element bonded together. It's right in the name: Di- ...

Atoms of antimatter and matter are perfect mirror images, even when weird quantum phenomena come into play. The energy levels of antihydrogen atoms — the antimatter opposites of hydrogen atoms — are ...

A model of a nanocluster catalyst featuring ruthenium atoms as green and white (with the white atoms highlighting the active centre) arranged as a flattened pyramid on a carbon support (represented by ...

Skoltech researchers and their colleagues from MIPT and China’s Center for High Pressure Science and Technology Advanced Research have computationally explored the stability of the bizarre compounds ...
