Quantum calculations amount to sophisticated estimates. But in 1931, Hans Bethe intuited precisely how a chain of particles ...

Forced to run a labyrinth of carbon atoms uniquely arranged in twisted stacks, electrons do some rather peculiar things.

Physicists measured how readily a current of electron pairs flows through 'magic-angle' graphene, a major step toward understanding how this unusual material superconducts. By determining how readily ...

But just as with carpools, how easily electron pairs can flow ... The material is effectively a single, atom-thin sheet of graphite consisting of a precise, chicken-wire lattice of carbon atoms. This ...

Matter and its nature, Dalton's atomic theory, Concept of atom ... electron gain enthalpy, valence, oxidation states and chemical reactivity. General Introduction: Electronic configuration ...

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

Bohr model of a hydrogen atom - its postulates, derivation of the relations for the energy of the electron and radii of the different orbits, limitations of Bohr's model, dual nature of matter ...

But what's an atom made of? What is matter ... charged particles move around into a lower-energy configuration. Similarly, matter can neither be created nor destroyed. But because of underlying ...

Along with Bohr’s theory of the quantum atom in 1913, the paper might be regarded as ... Pauli showed what this implied for the electron configurations of the noble gases, and it was immediately clear ...
