Seated at the head of the periodic table, hydrogen is the lightest element, a minimalist atom consisting only of a proton and an electron.

Static electricity works because electrons are strongly attracted to protons, right? But, in atoms, electrons are right there, next to the protons in the nucleus. Why don’t the electrons zip ...

There is so much more to these “negatively charged particles” than we've thought. You learned what an electron is in school… or DID YOU? You probably learned that it’s a “negatively ...

The 21-centimeter hydrogen line comes about when a hydrogen atom containing a proton/electron combination with aligned spins (top) flips to have anti-aligned spins (bottom), emitting one ...

If you expanded an atom to the size of a baseball, what would it look like? And how would the inside look if you sliced it open? The nucleus is the atom's central core and contains more than 99.9 ...

Measuring up: an electron scattering experiment yields a small proton radius. (Courtesy: Jefferson Lab) For nearly a decade the size of the particle that makes up the bulk of the universe’s visible ...

The Chlamydomonas reinhardtii proton gradient regulation5 (Crpgr5) mutant shows phenotypic and functional traits similar to mutants in the Arabidopsis (Arabidopsis thaliana) ortholog, Atpgr5, ...
