Part I, appearing in July 1913, described the quantum rules for electron orbits and quantum jumps in the hydrogen atom, explaining the spectrum of colors it emitted.

The largest Rydberg atoms have electron orbits with a diameter on the order of a micrometer, which means that something like 160 atoms are within the orbit when the Rydberg atom is formed.

DR. G. I. FINCH and A. G. QUARRELL1 have reported many extra rings in electron diffraction patterns from thin metal foils containing preferentially oriented crystals. At first they attributed ...

Atom swaps are part of a growing group of organic reactions used to alter a single atom in a larger, complex structure. Another atom-swapping reaction has entered the ring.

"So, I've seen the meme of 'Mods, add an electron to every atom in their body', and I know that its been asked here," Redditor Spectre1442 wrote in the AskPhysics subreddit. "So it got me thinking.

Consecutive extraction of single-atom and -electron for tailoring the gold nanoparticle magnetism and catalysis was achieved. view more . Credit: WU Zhikun.

Why saying who was first to split the atom is almost as hard as mastering atomic theory. Skip to content. ... discovered the electron, proving that the atom had smaller constituent parts.

The quantum fix. Famed Danish physicist Niels Bohr was the first person to propose a solution to this issue. In 1913, he suggested that electrons in an atom couldn't just have any orbit they wanted.

Heterocycles, molecular rings found in many pharmaceuticals, have a reputation for stubbornly resisting modification. That is, in a heterocycle, heteroatoms of one type aren’t easily swapped for ...

The electron from each atom feels the attraction from the proton in the nucleus of the other atom. This attraction pulls the atoms together and the electrons are shared by both atoms. The atoms bond ...
