How long does a free neutron really live before it decays? This simple question has annoyed physicists for decades. Moreover, ...

You could swim through the deepest voids and encounter a single hydrogen atom in an entire football field's worth of space.

A type of hydrogen that doesn't interact with light could explain how long neutrons live and reveal the identity of the ...

Five years later, scientists were able to peer inside a hydrogen atom using a "quantum microscope," resulting in the first direct observation of electron orbitals. And now we have the first X-ray ...

Project the animation Covalent bond in hydrogen. Make sure students see that each hydrogen atom has 1 proton and 1 electron. Remind students that the electron and its own proton are attracted to each ...

The chemical formula for water is H 2 O (two hydrogen atoms and one oxygen atom), and hydrogen water is simply water with more hydrogen (H) added to it. The concept seems to have started decades ...

Bohr tried to explain the connection between the distance of the electron from the nucleus, the electron's energy and the light absorbed by the hydrogen atom, using one great novelty of physics of ...
