Just a single foreign atom located in the vicinity of a molecule can change spatial arrangement of its atoms. In a spectacular experiment, an international team of researchers was able to change ...

GENEVAGENEVA — The world’s largest atom smasher used its accelerator Tuesday to speed up proton beams for the first time as scientists moved ahead in efforts to learn more about the universe. The $10 ...

Although tiny, a proton takes up a finite amount of space, enough to fit three quarks, a host of virtual particles, and their associated gluons. The size of a proton’s radius is determined by these ...

Atoms are very small. They have a radius of around 1 × 10 10 metres. This symbol shows that chlorine has 35 particles in the nucleus (protons and neutrons), 17 of which are protons. It also tells us ...

Measurement in ordinary hydrogen agrees with a surprising 2010 result on the element's exotic cousin — but gives a smaller value than virtually every other experiment. The proton might truly be ...

Ever wonder where the gold in your wedding ring came from? This Valentine's Day, we ask Neil deGrasse Tyson, director of New York City's Hayden Planetarium, to explain the history of the rare element.
