Democritus was born in 460 BC and died about 90 years later. He discovered that atoms were the building blocks of everything and that they were comprised of mostly space. "nothing exists except atoms and empty space, everything else is just opinion."]]> 2020-10-20 16:26:53 UTC https://padlet.com/anthonyhernandezmartinez6w/w4u2lhl1zjcarmqv/wish/845602643 https://padlet.com/anthonyhernandezmartinez6w/w4u2lhl1zjcarmqv/wish/845603612 Proposed by JJ Thomson in 1897. Won the Nobel prize in physics in 1906.]]> 2020-10-20 16:27:06 UTC https://padlet.com/anthonyhernandezmartinez6w/w4u2lhl1zjcarmqv/wish/845603612 https://padlet.com/anthonyhernandezmartinez6w/w4u2lhl1zjcarmqv/wish/845631198 Proposed by Ernest Rutherford in 1911, the model was based off of Thomson plum pudding experiments.

The electron was discovered by using the cathode ray tube experiment. The experiment works by Cathode ray tubes are sealed glass tubes from which most of the air has been evacuated. A high voltage is applied across two electrodes at one end of the tube, which causes a beam of particles to flow from the cathode and they used a magnet to see how the particles were charged and by using a positive magnet the found the negatively charged electron.]]> 2020-10-20 16:45:49 UTC https://padlet.com/anthonyhernandezmartinez6w/w4u2lhl1zjcarmqv/wish/845695803 https://padlet.com/anthonyhernandezmartinez6w/w4u2lhl1zjcarmqv/wish/845703105 Proposed by Erwin Schrödinger in 1926.

The polonium emitted alpha rays, which struck the beryllium. When struck, the beryllium emitted the mysterious neutral rays which lead him to believe that his hypothesis of neutrons existing and adding to the mass of an atom.]]> 2020-10-20 16:54:30 UTC https://padlet.com/anthonyhernandezmartinez6w/w4u2lhl1zjcarmqv/wish/845739447
