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 ...

George W. Bush made hydrogen his baby back in the early 2000's, but this alternative fuel could still have its day in the sun.

Hydrogen is by far the most abundant element in the universe. It constitutes roughly 90 percent of atoms in the Sun and in most stars. Helium ranks second, with nearly 9 percent. This leaves only 1 ...

Now scientists are turning to wastewater as a viable source of hydrogen. They have discovered a way to extract hydrogen more ...

An infinite chain of hydrogen atoms is just about the simplest bulk material imaginable -- a never-ending single-file line of protons surrounded by electrons. Yet a new computational study combining ...
