fabrication-the act of making something (a product) from raw materials; the synthesis and fabrication of single crystals; an improvement in the manufacture of explosives; manufacturing is vital to Great Britain.
The Auger effect /oÊËÊÉr/ is a physical phenomenon in which the filling of an inner-shell vacancy of an atom is accompanied by the emission of an electron from the same atom.n electron from the 2s level fills in the 1s hole and the transition energy is imparted to a 2p electron which is emitted. The final atomic state thus has two holes, one in the 2s orbital and the other in the 2p orbital.
A valence electron is an electron in the outermost electron shell of a representative element or noble gas element. The number of valence electrons in a representative element can be determined by its electronic configuration. For elements in Groups IIIA through VIIIA the outermost s and p electrons in the highest energy shell are valence electrons. 2  For transition elements the valence electrons are those in the outermost s sub-shell and in the d sub-shell of the next to outermost energy shell.
