He developed the concept of the atom
his experiment was he took a seashell and kept on breaking it up]]> 2018-11-05 16:00:31 UTC https://padlet.com/belisjos000/br4evx0lukjn/wish/300543534 belisjos000 https://padlet.com/belisjos000/br4evx0lukjn/wish/300547515 discoverd in 1803
his discovery was that ell elements were made out of atoms

Experiments with gases that first became possible at the turn of the nineteenth century led John Dalton in 1803 to propose a modern theory of the atom based on the following assumptions. 1. Matter is made up of atoms that are indivisible and indestructible.]]> 2018-11-05 16:05:32 UTC https://padlet.com/belisjos000/br4evx0lukjn/wish/300547515 niharjac000 https://padlet.com/belisjos000/br4evx0lukjn/wish/300549120 1856 - 1940
He discovered the electron

his experiment was to rub items together to gain a charge and attracted a negative charge]]> 2018-11-05 16:07:48 UTC https://padlet.com/belisjos000/br4evx0lukjn/wish/300549120 niharjac000 https://padlet.com/belisjos000/br4evx0lukjn/wish/300551805 1913
The atoms can only jump energy levels whole increments at a time

Stairs you can only go up whole stairs at a time like energy levels in an atom]]> 2018-11-05 16:11:49 UTC https://padlet.com/belisjos000/br4evx0lukjn/wish/300551805 belisjos000 https://padlet.com/belisjos000/br4evx0lukjn/wish/300551963 Year of discover was 1911
he discovered the atomic nucleus

Rutherford's Gold Foil Experiment proved the existence of a small massive center to atoms, which would later be known as the nucleus of an atom. Ernest Rutherford, Hans Geiger and Ernest Marsden carried out their Gold Foil Experiment to observe the effect of alpha particles on matter.]]> 2018-11-05 16:12:02 UTC https://padlet.com/belisjos000/br4evx0lukjn/wish/300551963 belisjos000 https://padlet.com/belisjos000/br4evx0lukjn/wish/300554494 his year of discover was 1932
he discovered the neutron
James Chadwick was assigned the task of tracking down evidence of Rutherford's tightly bound "proton-electron pair" or neutron. In 1930 it was discovered that Beryllium, when bombarded by alpha particles, emitted a very energetic stream of radiation.]]> 2018-11-05 16:15:28 UTC https://padlet.com/belisjos000/br4evx0lukjn/wish/300554494 niharjac000 https://padlet.com/belisjos000/br4evx0lukjn/wish/300558212 2018-11-05 16:20:23 UTC https://padlet.com/belisjos000/br4evx0lukjn/wish/300558212 niharjac000 https://padlet.com/belisjos000/br4evx0lukjn/wish/300563702 2018-11-05 16:27:09 UTC https://padlet.com/belisjos000/br4evx0lukjn/wish/300563702 niharjac000 https://padlet.com/belisjos000/br4evx0lukjn/wish/305919461 2018-11-19 14:07:44 UTC https://padlet.com/belisjos000/br4evx0lukjn/wish/305919461 niharjac000 https://padlet.com/belisjos000/br4evx0lukjn/wish/305919951 2018-11-19 14:08:25 UTC https://padlet.com/belisjos000/br4evx0lukjn/wish/305919951 niharjac000 https://padlet.com/belisjos000/br4evx0lukjn/wish/305920581 2018-11-19 14:09:16 UTC https://padlet.com/belisjos000/br4evx0lukjn/wish/305920581 niharjac000 https://padlet.com/belisjos000/br4evx0lukjn/wish/305921081 2018-11-19 14:09:55 UTC https://padlet.com/belisjos000/br4evx0lukjn/wish/305921081
