...three general addresses were made by 1) Robert A. Millikan, Professor of Physics, California Institute of Technology, and Nobel prizewinner for 1923, on The Atom as Seen by the Physicist. 2) Dr. Gilbert N. Lewis, Professor of Chemistry, University of California, on The Atom as Seen by the Chemist. 3) Dr. Edwin E. Slosson, Director of Science Service, and author of Creative Chemistry, on The Expansion of Chemistry. The Society also divided into the following general divisions, as well as many smaller sections: chemistry of medicinal products; organic chemistry; industrial and engineering chemistry; physical and inorganic chemistry...
...scientists agree upon an atom which has a very minute, positively charged nucleus, neutralized by a number of negative electrons which surround it. The nucleus has always a definite number of positive charges upon it, varying from one (hydrogen) to 92 (uranium). Outside the nucleus are the negative electrons, varying in number in the same way. The outermost layer of these are the valence electrons, which mingle with those of other atoms in the process of combination. So far as physical science has gone, there have appeared but two fundamental entities, positive and negative electrons?the building stones...
...Willard Gibbs medal in physical chemistry, upheld the magnetic nature of the electrons, which, like any other current of electricity, become magnets when moving in circles. They travel in pairs, 180 degrees apart, neutralizing each other, and thus holding together all chemical compounds. Instead of the Bohr atom with its positive nucleus, Dr. Lewis claimed that the electrons, though having orbits, do not revolve around the "kernel" of the atom. No one has been able to work out a satisfactory path for these paired electronic orbits, but that fact does not bother the chemists so much as the physicists. Instead...
...atomic theory and its relation to heat, since burning involves the transfer of electrons from one atom to another," said Professor Lamb, "will form the basis for the new discoveries in the chemical constitution of heat which are sure to be made in the near future...
