From The Collaborative International Dictionary of English v.0.48 :

  Atomic \A*tom"ic\, Atomical \A*tom"ic*al\, a. [Cf. F. atomique.]
     1. Of or pertaining to atoms.
        [1913 Webster]
  
     2. Extremely minute; tiny.
        [1913 Webster]
  
     Atomic bomb, see atom bomb in the vocabulary.
  
     Atomic philosophy, or Doctrine of atoms, a system which,
        assuming that atoms are endued with gravity and motion,
        accounted thus for the origin and formation of all things.
        This philosophy was first broached by Leucippus, was
        developed by Democritus, and afterward improved by
        Epicurus, and hence is sometimes denominated the Epicurean
        philosophy.
  
     Atomic theory, or the Doctrine of definite proportions
        (Chem.), teaches that chemical combinations take place
        between the supposed ultimate particles or atoms of
        bodies, in some simple ratio, as of one to one, two to
        three, or some other, always expressible in whole numbers.
        
  
     Atomic weight (Chem.), the weight of the atom of an element
        as compared with the weight of the atom of hydrogen, taken
        as a standard.
        [1913 Webster]

From The Jargon File (version 4.4.7, 29 Dec 2003) :

  atomic
   adj.
  
      [from Gk. atomos, indivisible]
  
      1. Indivisible; cannot be split up. For example, an instruction may be said
      to do several things ?atomically?, i.e., all the things are done
      immediately, and there is no chance of the instruction being half-completed
      or of another being interspersed. Used esp. to convey that an operation
      cannot be screwed up by interrupts. ?This routine locks the file and
      increments the file's semaphore atomically.?
  
      2. [primarily techspeak] Guaranteed to complete successfully or not at all,
      usu. refers to database transactions. If an error prevents a
      partially-performed transaction from proceeding to completion, it must be ?
      backed out?, as the database must not be left in an inconsistent state.
  
      Computer usage, in either of the above senses, has none of the connotations
      that ?atomic? has in mainstream English (i.e. of particles of matter,
      nuclear explosions etc.).
  

From The Free On-line Dictionary of Computing (18 March 2015) :

  atomic
  
      (From Greek "atomos", indivisible) Indivisible;
     cannot be split up.
  
     For example, an instruction may be said to do several things
     "atomically", i.e. all the things are done immediately, and
     there is no chance of the instruction being half-completed or
     of another being interspersed.  Used especially to convey that
     an operation cannot be interrupted.
  
     An atomic data type has no internal structure visible to the
     program.  It can be represented by a flat domain (all
     elements are equally defined).  Machine integers and
     Booleans are two examples.
  
     An atomic database transaction is one which is guaranteed to
     complete successfully or not at all.  If an error prevents a
     partially-performed transaction from proceeding to completion,
     it must be "backed out" to prevent the database being left in
     an inconsistent state.
