He discovered the electron . In Cambride,England at Trinity college. The atom is composed of electrons .]]> 2016-08-22 15:17:51 UTC https://padlet.com/akimbrell/2ndblock/wish/119175811 https://padlet.com/akimbrell/2ndblock/wish/119175873 He introduced the idea of the atom as the basic building block matter. He thought that atoms are tiny, uncuttable, solid particles that are surrounded by empty space and constantly moving at random. He also thought that atoms are indestructible. His theory was that atoms differ in size, shape, mass, position, and arrangement.]]> 2016-08-22 15:17:58 UTC https://padlet.com/akimbrell/2ndblock/wish/119175873 https://padlet.com/akimbrell/2ndblock/wish/119176351 Developed the Bohr model of the atom that proposed that energy levels of electrons are discrete and follow stable levels. It was a crude model of the hydrogen atom.]]> 2016-08-22 15:19:21 UTC https://padlet.com/akimbrell/2ndblock/wish/119176351 https://padlet.com/akimbrell/2ndblock/wish/119177722 Best known for pioneering work in development of modern atomic theory. He said all matter is made up of atoms. And atoms are invisible and indestructible. He also said that compounds are formed by a combo and are made with 2 different kinds of atoms. ]]> 2016-08-22 15:23:21 UTC https://padlet.com/akimbrell/2ndblock/wish/119177722 dwalker490 https://padlet.com/akimbrell/2ndblock/wish/119178020 Discovered the mass and charge of the electrons.
