With einsteinium plus calcium off the table, three other combinations of nuclei are being considered as hot-fusion candidates to create element 119. Each pairing produces an atom with 119 protons ...

Will Norman asks if mass-scale deployment of perovskite technology is now imminent and whether it could unseat crystalline ...

The periodic table organizes chemical elements based on atomic weight, electron configurations, and chemical properties, ...

Skimmed milk has a little more calcium than semi-skimmed, which in turn has a little more calcium than whole milk. The reason is simply that as the fat is removed, the watery proportion of the ...

All humans need clean water to live. However, purifying water can be energy-intensive, and therefore there is great interest ...

When atoms collide, their exact structure—for example, the number of electrons they have or even the quantum spin of their ...

A difficulty arises when we come to potassium. Potassium has an atomic number of 19. For potassium and calcium, the 4s orbital dips in energy below the 3d orbitals, and so electrons go into the 4s ...

J.J. Thomson — a professor of experimental physics at the University of Cambridge, who in 1897 discovered the electron and in 1904 proposed a model of the atom — was the first person to be ...

A small town mayor in New Zealand has picked a nuclear fight with Donald Trump, after the freshly sworn-in U.S. president heaped praise on American scientists for splitting the atom. The mayor of ...
