Atomic mass constant — In physics and chemistry, the atomic mass constant, m u, is one twelfth of the mass of an unbound atom of the carbon 12 nuclide at rest and in its ground state. [GoldBookRef|title=atomic mass constant|url=http://goldbook.iupac.org/A00497.html] It … Wikipedia
Atomic units — (au) form a system of units convenient for atomic physics, electromagnetism, and quantum electrodynamics, especially when the focus is on the properties of electrons. There are two different kinds of atomic units, which one might name Hartree… … Wikipedia
Atomic orbital — The shapes of the first five atomic orbitals: 1s, 2s, 2px, 2py, and 2pz. The colors show the wave function phase. These are graphs of ψ(x,y,z) functions which depend on the coordinates of one electron. To see the elongated shape of ψ(x,y,z)2… … Wikipedia

Atomic formula — In mathematical logic, an atomic formula (also known simply as an atom) is a formula with no deeper propositional structure, that is, a formula that contains no logical connectives or equivalently a formula that has no strict subformulas. Atoms… … Wikipedia
Ground expression — In mathematical logic, a ground term of a formal system is a term that does not contain any variables at all, and a closed term is a term that has no free variables. In first order logic all closed terms are ground terms, but in lambda calculus… … Wikipedia
Atomic emission spectrum — The atomic emission spectrum of an element is the set of frequencies of the electromagnetic waves emitted by atoms of that element. Each atom s atomic emission spectrum is unique and can be used to determine if that element is part of an unknown… … Wikipedia
List of fictional elements, materials, isotopes and atomic particles — This list contains chemical elements, materials, isotopes or (sub)atomic particle that exist primarily in works of fiction (usually fantasy or science fiction). No actual periodic elements end in ite , though many minerals have names with this… … Wikipedia
Rydberg constant — The Rydberg constant, named after the Swedish physicist Johannes Rydberg, is a physical constant relating to atomic spectra in the science of spectroscopy. Rydberg initially determind its value empirically from spectroscopy, but then later, it… … Wikipedia
