Atomic theory — Atomic model redirects here. For the unrelated term in mathematical logic, see Atomic model (mathematical logic). This article is about the historical models of the atom. For a history of the study of how atoms combine to form molecules, see… … Wikipedia
Atomic sentence — In logic, an atomic sentence is a type of declarative sentence which is either true or false (may also be referred to as a proposition, statement or truthbearer) and which cannot be broken down into other simpler sentences. For example The dog… … Wikipedia
Atomic mass — The atomic mass (ma) is the mass of an atom, most often expressed in unified atomic mass units. [GoldBookRef|file=A00496|title=atomic mass] The atomic mass may be considered to be the total mass of protons, neutrons and electrons in a single atom … 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

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
Atomic carbon — This very short lived species is created by passing a large current through two adjacent carbon rods, generating an electric arc. Atomic carbon is generated in the process. Professor Phil Shevlin has done the principal work in the field based at… … Wikipedia
Compound semiconductor — A compound semiconductor is a semiconductor compound composed of elements from two or more different groups of the periodic table [1]. These semiconductors typically form in groups 13 16 (old groups III VI), for example of elements from group 13… … Wikipedia
