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 ...

A single speck of light—captured inside a lab at Oxford—turned the abstract into the tangible. It didn’t just win a prize; it ...

Electron capture processes in ion–atom collisions constitute a critical phenomenon in understanding the interplay between charged particles and neutral atoms. In these collisions, an ion may capture ...

When building an atom, pay close attention to the particles' electrical charges. Protons have a charge of +1. Electrons have a charge of -1. Neutrons are neutral, as their name implies. A stable atom ...

Sometimes, all it takes to capture a great photo is a DSLR camera, a microscopic atom, and a curious Ph.D. candidate. David Nadlinger, who traps atoms for his quantum computing research at the ...

An image of a single atom of the metal strontium suspended in electric fields has won the 2018 Engineering and Physical Sciences Research Council science photography competition. David Nadlinger‘s ...
