-Dalton’s atom indivisible -electricity Faraday electrolysis: 2H 2 O –elect.--> 2H 2 +O 2 (electricity, breaking) -found Li, Na, K…elements that usually exist as compounds electrolyte-can carry electricity generally dissolved in water -atoms have electrical “charged” native cathode rays: from cathode in a vacuum -candeflect rays with magnet, must have negative charge J.J. Thompson-matrix (+) with embedded (-) electrons, overall neutral charge Millikan’s oil drop- vary charge on plates, get drops to hover, could calc charge Rutherford-gold foil exp. -smallest nucleus H atom (nucleus= 1 proton, atom= 1 proton, 1 electron) -nucleus also has neutrons neutral ~mass as protons -atomic symbols Where are e-? pure Ne or Hg or Ar or H give light when e- run through Bohr’s model e- only have certain allowed energy and certain positions -energy levels around nucleus further from nuc. High e -E into e- raises level -each change in E down gives off E as light -different E give different colors
