Atomic weight — (symbol: A sub|r) is a dimensionless physical quantity, the ratio of the average mass of atoms of an element (from a given source) to 1/12 of the mass of an atom of carbon 12.cite journal | author = International Union of Pure and Applied… … 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 operation — An atomic operation in computer science refers to a set of operations that can be combined so that they appear to the rest of the system to be a single operation with only two possible outcomes: success or failure.ConditionsTo accomplish this,… … Wikipedia
atomic weight — Chem. the average weight of an atom of an element, formerly based on the weight of one hydrogen atom taken as a unit or on 1/16 the weight of an oxygen atom, but after 1961 based on 1/12 the weight of the carbon 12 atom. Abbr.: at. wt. [1820 30]… … Universalium
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
