Some articles on atoms, atom:

Azane - Isomerism
... Azanes with more than three nitrogen atoms can be arranged in various different ways, forming structural isomers ... isomer of an azane is the one in which the nitrogen atoms are arranged in a single chain with no branches ... However the chain of nitrogen atoms may also be branched at one or more points ...
Sigmatropic Reaction - Overview of Sigmatropic Shifts - Woodward-Hoffman Sigmatropic Shift Nomenclature
... or more π systems to a new position (i-1) and (j-1) atoms removed from the original location of the σ-bond ... an even number, this is an indication of the involvement of a neutral, all C atom chain ... is an indication of the involvement of a charged C atom or of a heteroatom lone pair replacing a CC double bond ...
Antiprotonic Helium - Laser Spectroscopy
... Antiprotonic helium atoms are under study by the ASACUSA experiment at CERN ... In these experiments, the atoms are first produced by stopping a beam of antiprotons in helium gas ... The atoms are then irradiated by powerful laser beams, which cause the antiprotons in them to resonate and jump from one atomic orbit to another ...

Famous quotes containing the word atoms:

    Moreover, the universe as a whole is infinite, for whatever is limited has an outermost edge to limit it, and such an edge is defined by something beyond. Since the universe has no edge, it has no limit; and since it lacks a limit, it is infinite and unbounded. Moreover, the universe is infinite both in the number of its atoms and in the extent of its void.
    Epicurus (c. 341–271 B.C.)

    Scatter my ashes, strew them in the air:
    Lord since thou know’st where all these atoms are,
    I’m hopeful thou’lt recover once my dust,
    And confident thou’lt raise me with the just.
    —James Graham Marquess of Montrose (1612–1650)

    [Humanity] has unquestionably one really effective weapon—laughter. Power, money, persuasion, supplication, persecution—these can lift at a colossal humbug—push it a little—weaken it a little, century by century; but only laughter can blow it to rags and atoms at a blast. Against the assault of laughter nothing can stand.
    Mark Twain [Samuel Langhorne Clemens] (1835–1910)
