Just about everyone knows that water is H2O, meaning two hydrogen atoms and one oxygen atom. What might surprise people is that scientists have never before been able to actually watch hydrogen ...

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 ...

Like ordinary water—H 2 0—each molecule of heavy water contains two hydrogen atoms and one oxygen atom. The difference, though, lies in the hydrogen atoms. In ordinary water, each hydrogen ...

Water may have formed less than 200 million years after the Big Bang, suggesting some conditions for life existed far earlier than previously thought.

confine and then study antihydrogen atoms, with studies taking two forms primarily. One is the spectroscopy of the internal structure, the internal energy levels of the anti-hydrogen atom to ...
