...beta rays (electrons, negatively charged particles) rat-tat-tat-ing against the atoms of elements might conceivably change those elements into new and precious forms. Mercury might yet become gold, as alchemists dreamed. Theoretically the procedure is simple. An atom of mercury contains at its centre, 198 protons (positively charged particles) and 118 electrons. Around that nucleus swirl 80 more electrons. These complete the mercury balance of 198 electrons against 198 protons. An atom of gold contains 197 protons and 118 electrons in its nucleus and 79 more electrons shooting around them. If it becomes possible for the beta particles...
Another profound fact Professor Compton discovered. Atoms are made up of a nucleus with a positive charge of electricity and one or more electrons with negative charges. The electrons (they are all the same size no matter what the element) revolve around their nucleus in a symmetrical pattern. Hydrogen, lightest of elements, has only one electron whirling around its nuclear "sun." Heavy metals, like lead, radium and uranium, have many electrons. In some elements some of the electrons pop away from their atoms. Such elements are radioactive. X-rays can make them pop away violently. When x-rays...
Movies. In the Nittany Theatre, where Penn State undergraduates stamp their feet and throw peanuts at the shadows of Harold Lloyd and Gloria Swanson, the chemists admired cinematic views of chemical wonders. A strip of animated drawings designed and presented by the General Electric Co. projected the electron theory of atoms into visible action, showing protons and their spinning satellites moving about to form molecular cubes, circles, chains, polymorphs...
...Robert Andrew Millikan, famed physicist, first isolated the electron, detected the cosmic pulse that throbs in the solar systems of broad-girthed planets and infinitesimal atoms alike. Like Master Electrician Steinmetz, this man of twinkling blue-grey eyes and sparkling wit knows how to make scientific complexities charming as well as awesome. For weeks past in the North, South, East and West he has lectured to make laymen see the unity of movement and purpose in the cosmos enveloping the universe...
...Henry Huxley (Evolution), "in these days of manifold information and broadcast amusement, that the world will become divided into those who have to think for their living and those who never think at all." Hence?and because the layman, while he is knowing and kindly towards an atom or electron when he meets one, is embarrassed by sperms and ova and benighted as to chromosomes?hence another volume of popular biology...
