Show SCIENCE SEEKS NEW ELEMENTS Chemist Says Matter Is Empty All Electrons Similar LOS IOS ANGELES A GELES Calif Aug 4 4 A There P are probably three more elements clements to bo be discovered was tho the prediction ventured by Dr Br Willis R. R Whitney of the tho General Electric company Schenectady Schenectady N. N Y V. In an nn s addres s before the American Chemical society to to to- night Discussing DI Matter Matter JA Is There Anything In It ho he said 1111 science now has reached n n. stage where a physical picture of tho the structure of atoms atom Is I more Intricate Intricate intricate cate than any earthly model and more perfect geometrically than any known n celestial c lIal system S I Making new generalizations gS from the work of J. J J. J Thomson and R. R A A. Millikan Dr Whitney said MATTER IS EMPTY Matter Iatter Is at least not merely dry and hard nor yet jet soft and an 1 wet It Is electronic and celestial l. er whatever that may mon moan and the most wo 0 know about it Is that It Itis ItIs Itis is almost entirely space It is III as empty as tho the sky It Is almost as fth empty YIt as a a perfect C f vacuum c I although It usually sall contains al a lot lotof lotof i of energy I All AlI the tho elements from the smallest to 10 the largest the speak speak- speaker I er or declared can be constructed by orderly assemblies of positive and negative n a electrons e Of the I atom he said its I actual smallness is Impossible to realize but so much seems known of Its Us dimen dimen- dimensions that we wo must accept it and try tr to apply It ItA ItA itA A molecule of water Dr Whitney Illustrated contains two o atoms of hydrogen Suppose we ise e eI I start with ono one single drop nf f I I water and let all of Its hydrogen atoms appear In turn as all drops of oC I water If It these were as large as a raindrops they could cover tho the whole holc world with a a. foot of wa wa- a ter SIZE Another illustration which Dr Whitney gave was that If one oT of 0 these hydrogen atoms were vere made so large that It became a yard ard in diameter Its Ha electron still would bo be only a pinhead in size and ltd its I nucleus 2000 times smaller The he speaker described com coot composition composition position of matter as the chemist now sees It and demonstrated by experiments the realities of the them unimaginably m g n small m 1 particles r le Ho Lie said I he ho wanted te to go as tar far r as ashe 1 he ho could In pointing out the vacuity of matter aa as scientists persist In speculating and expert experimenting on the atom because everything wo know lenow is made mado of or atoms There are only a II very limited number of different kinds said Dr Whitney These explain all differences we can call probably ever know In our uni uni- verse Thus far the th more we have ha sought to understand there their tho the more wo we have gained In ap appreciation ap- ap predatIon of an unexplored un un- unlimited unlimited Unlimited limited territory of interest and service ser PERIODIC LAW W.
