But what about pseudo-atoms, a.k.a. those molecular fragments that don't change much in various environments and are considered to behave like atoms? Scientists at Pacific Northwest National Laboratory and Heriot-Watt University in Scotland put the tetrahedral ammonium radical, made from a nitrogen atom and four hydrogen atoms, on the electronegativity scale. It has the same attractive force as potassium and has the same size as an atom of rubidium. irishdancer0215 Sun, 08 Jan 2012 23:44:15 GMT http://chemistry.about.com/library/blstructures.htm irishdancer0215 Tue, 28 Mar 2006 04:10:37 GMT
