Some articles on atoms, atom:
... 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 ...
... Azanes with more than three nitrogen atoms can be arranged in various different ways, forming structural isomers ... The simplest 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 ...
... to one or more π systems to a new position (i-1) and (j-1) atoms removed from the original location of the σ-bond ... of i and j is an even number, this is an indication of the involvement of a neutral, all C atom chain ... An odd number is an indication of the involvement of a charged C atom or of a heteroatom lone pair replacing a CC double bond ...
... Each gallium atom is tetrahedrally coordinated by 3 tellurium and one gallium atom ... The core consists of a cube of eight atoms, four gallium, and four tellurium atoms ... an attached t-butyl group and three adjacent tellurium atoms and each tellurium has three adjacent gallium atoms ...
... formula C5H10 and CAS number 287-92-3, consisting of a ring of five carbon atoms each bonded with two hydrogen atoms above and below the plane ... in the class of cycloalkanes, being alkanes that have one or more rings of carbon atoms ...
Famous quotes containing the word atoms:
“No imperfection in budded mountain,
Valleys breathe, heaven and earth move together,
daisies push inches of yellow air, vegetables tremble,
green atoms shimmer in grassy mandalas,
sheep speckle the mountainside, revolving their jaws with empty eyes,
horses dance in the warm rain,”
—Allen Ginsberg (b. 1926)
“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. 341271 B.C.)
“Scatter my ashes, strew them in the air:
Lord since thou knowst where all these atoms are,
Im hopeful thoult recover once my dust,
And confident thoult raise me with the just.”
—James Graham Marquess of Montrose (16121650)
