Discovers everything is composed of atoms
He contributed to the theory of atomism, propounded by his teacher Leucippus, by suggesting that all matter consisted of tiny, indivisible particles.

Discovers electrons by experimenting with a Crookes, or cathode ray, tube. He demonstrated that cathode rays were negatively charged.]]> 2018-10-08 14:27:15 UTC https://padlet.com/bonhamtraberc/fwnww9cjrxjf/wish/290319154 bonhamtraberc https://padlet.com/bonhamtraberc/fwnww9cjrxjf/wish/290320056 Dimitri Mendeleev
Listed elements in atomic weight and put them into columns
He arranged the elements known at the time in order of relative atomic mass ]]> 2018-10-08 14:28:31 UTC https://padlet.com/bonhamtraberc/fwnww9cjrxjf/wish/290320056 bonhamtraberc https://padlet.com/bonhamtraberc/fwnww9cjrxjf/wish/290326955 Ernest Rutherford
First one to split atom, demonstrated that a atom has a tiny, heavy nucleus
Ernest and his team of scientists shot alpha particles at aluminum foil and found the nucleus]]> 2018-10-08 14:41:48 UTC https://padlet.com/bonhamtraberc/fwnww9cjrxjf/wish/290326955 bonhamtraberc https://padlet.com/bonhamtraberc/fwnww9cjrxjf/wish/298034092 Erwin Shrodinger
Made an atomic model called the Quantum Mechanical model of an atom
It came as a result of his dissatisfaction with the quantum condition in Bohr's orbit theory and his belief that atomic spectra should really be determined by some kind of eigenvalue problem.]]> 2018-10-29 14:17:00 UTC https://padlet.com/bonhamtraberc/fwnww9cjrxjf/wish/298034092 bonhamtraberc https://padlet.com/bonhamtraberc/fwnww9cjrxjf/wish/298036722 John Dalton
Created the first chart of atomic weights 
He discovered this theory while experimenting with gases]]> 2018-10-29 14:21:02 UTC https://padlet.com/bonhamtraberc/fwnww9cjrxjf/wish/298036722 bonhamtraberc https://padlet.com/bonhamtraberc/fwnww9cjrxjf/wish/298039510 Niels Bohr
Developed the Bohr model, he proposed that energy levels of electrons are discrete and that electrons revolve in stable orbits]]> 2018-10-29 14:25:06 UTC https://padlet.com/bonhamtraberc/fwnww9cjrxjf/wish/298039510 bonhamtraberc https://padlet.com/bonhamtraberc/fwnww9cjrxjf/wish/298041387 2018-10-29 14:28:08 UTC https://padlet.com/bonhamtraberc/fwnww9cjrxjf/wish/298041387 bonhamtraberc https://padlet.com/bonhamtraberc/fwnww9cjrxjf/wish/298041796 2018-10-29 14:28:48 UTC https://padlet.com/bonhamtraberc/fwnww9cjrxjf/wish/298041796 bonhamtraberc https://padlet.com/bonhamtraberc/fwnww9cjrxjf/wish/298042313 2018-10-29 14:29:39 UTC https://padlet.com/bonhamtraberc/fwnww9cjrxjf/wish/298042313 bonhamtraberc https://padlet.com/bonhamtraberc/fwnww9cjrxjf/wish/298043186 2018-10-29 14:30:57 UTC https://padlet.com/bonhamtraberc/fwnww9cjrxjf/wish/298043186 bonhamtraberc https://padlet.com/bonhamtraberc/fwnww9cjrxjf/wish/298043487 2018-10-29 14:31:23 UTC https://padlet.com/bonhamtraberc/fwnww9cjrxjf/wish/298043487 bonhamtraberc https://padlet.com/bonhamtraberc/fwnww9cjrxjf/wish/298043978 2018-10-29 14:32:03 UTC https://padlet.com/bonhamtraberc/fwnww9cjrxjf/wish/298043978 bonhamtraberc https://padlet.com/bonhamtraberc/fwnww9cjrxjf/wish/298044317 2018-10-29 14:32:33 UTC https://padlet.com/bonhamtraberc/fwnww9cjrxjf/wish/298044317
