Bohr proposed adding to the model the new idea of quanta put forth by Max Planck in 1901. That way, electrons existed at set levels of energy, that is, at fixed distances from the nucleus.

Analysis suggests that the two pioneers of quantum mechanics, Niels Bohr and John von Neumann, may have had more similar ...

In 1912 Bohr joined Rutherford. He realized that Rutherford's model wasn't quite right. By all rules of classical physics, it should be very unstable. For one thing, the orbiting electrons should ...

Fluorine's name derives from fluorspar — or fluorite, CaF 2 (pictured) — which in earlier times was used as a flux to facilitate smelting. As early as the seventeenth century, fluorspar was ...

Since their clinical use initiation in the 1970’s, Fluorine-18 (F-18) radiopharmaceuticals continue to play an important role in nuclear medicine. It is therefore essential to make available broad ...

You’re trying to impress your chemistry class crush or your significant other who appreciates science as much as you do.

The Fluorine Group is one of the RSC's many Interest Groups. The Interest Groups are member driven groups which exist to benefit RSC members, and the wider chemical science community, in line with the ...

Model portfolios continue to expand, increasing to nearly $424 billion USD. Assets in model portfolios have surged by 48% over two years, reflecting their growing popularity and effectiveness in ...

It produces hydrofluoric acid and other fluorine chemicals; and synthetic cryolite and fluorocarbon gases. It operates through the following segments: refrigerants, specialty fluor chemicals ...

In other words, all it takes for a molecule to belong in the PFAS category is a single carbon atom bound to two or three fluorine atoms and not bound to any other halogen or to hydrogen anywhere ...
