Since the atomic nucleus was first proposed in 1911, physicists simply assumed it was round. ​ But are the nuclei of atoms ...

Today, this model is known as the quantum model or the electron cloud model. The inner orbitals surrounding the atom are spherical but the outer orbitals are much more complicated. An atom's ...

At the subatomic level, particles interact not only with one another, but with the quantum ... an electron not as a particle when it’s in a hydrogen atom, but rather as a “probability cloud ...

They realized that each atom had a dense, heavy, positively charged nucleus surrounded by a cloud of tiny ... An orbiting electron, if it followed this solar system model, would instead emit ...

When two-dimensional electron systems are subjected to magnetic fields at low temperatures, they can exhibit interesting ...

“And there would be a large volume all around it that’s mostly empty space… If I were to model ... atom has a unique fingerprint.” To make things a little weirder, the electron cloud ...

What you’re looking at is the first direct observation of an atom’s electron orbital — an atom’s actual wave function! To capture the image, researchers utilized a new quantum microscope ...

A quantum computer has used a single atom to model the complex dynamics of organic molecules interacting with light ...

By the start of the 20th century, physicists knew that atoms had electrically charged parts; the favorite model ... the quantum rules for electron orbits and quantum jumps in the hydrogen atom ...

Our theoretical model describes the experimental ... that's ruled out by the laws of quantum mechanics. But what they did see is how the electron cloud "migrated" within the molecule.
