... separate regions of an atomic cloud, and then retrieving them — could be a fillip for applications, among them quantum cryptography. On page 67 of this issue, Choi et al.1 recount how they store two ‘entangled’ photon states in a memory consisting of a cloud of cold atoms, and then, after a certain ...

The Aufbau principle determines an atom`s electron
... The Aufbau principle is based on the idea that the order of orbital energies is fixed—both for a given element and between different elements. This assumption is approximately true— enough for the principle to be useful—but not physically reasonable. It models atomic orbitals as "boxes" of fixed en ...

Hydrogen atom
A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the elemental (baryonic) mass of the universe.In everyday life on Earth, isolated hydrogen atoms (usually called ""atomic hydrogen"" or, more precisely, ""monatomic hydrogen"") are extremely rare. Instead, hydrogen tends to combine with other atoms in compounds, or with itself to form ordinary (diatomic) hydrogen gas, H2. ""Atomic hydrogen"" and ""hydrogen atom"" in ordinary English use have overlapping, yet distinct, meanings. For example, a water molecule contains two hydrogen atoms, but does not contain atomic hydrogen (which would refer to isolated hydrogen atoms).
