He concluded that the various compounds are combinations of atoms of different elements with a particular size and mass that cannot be either created or destroyed]]> 2023-09-28 00:18:27 UTC https://padlet.com/3861022/4xn9hb4p3zr79r8g/wish/2723896226 3861022 https://padlet.com/3861022/4xn9hb4p3zr79r8g/wish/2723903508 Founded the electrons and described them as a Chocolate Chip cookie model. Atoms were uniformly packed spheres of positive matter filled with negitively charged electrons ]]> 2023-09-28 00:26:40 UTC https://padlet.com/3861022/4xn9hb4p3zr79r8g/wish/2723903508 3861022 https://padlet.com/3861022/4xn9hb4p3zr79r8g/wish/2723915041 Rutherford was the fisrt known father of the nuclear age. Shot small positiviley charged alpha particles at Gold foil. Rutherfor concluded that atoms consisted of just mostly empty space. These atoms only had a few electrons on the outside and the mass in the middle which he called the Nucleus.]]> 2023-09-28 00:40:38 UTC https://padlet.com/3861022/4xn9hb4p3zr79r8g/wish/2723915041 3861022 https://padlet.com/3861022/4xn9hb4p3zr79r8g/wish/2723916081 Stated that the electrons orbit the nucleus at fixed energies and distances. Able to jump from one level of orbit to another but not to exist inbetween.
