Answer Key For Atomic Timeline Events In

Model, the atom was like a plum pudding it was mostly a thick, positively charged material, with negative electrons scattered about it like plumsin a pudding In 908, Ernest Rutherford took an extremely thin sheet of gold foil and bombarded it with electrons Much to his surprise, most of the electrons went right through the foil, and the occasional bullet or electron was seriouslyAtomic Theory Timeline The atomic model has changed over time For over two centuries, scientists have created different models of the atom As scientists have learned more and more about atoms, the atomic model has changed Atomic Theory Timeline Here is a timeline of some of the major ideas Dalton Thomson Rutherford Bohr Chadwick Modern But First, Democritus!
