Joseph John Thomson -1897 England He discovered that atoms contained electrons through his explorations on the properties of cathode rays. He concluded that the rays were composed of very light, negatively supercharged particles. We now know that an atom contains electrons and we know the social organization of an electron overcloud and how many electrons each shell of the cloud sess hold.

Democritus- 460 BC Greece He developed the idea of atoms. He position that at some point, a substance wouldnt be able to be split in one-half any longer and he called these basic matter particles atoms.

John Dalton-1803 England He started using symbols to even out the atoms of different elements. The logbook entry called Observations on the Ultimate Particles of Bodies and their Combinations had the first practice of symbols to represent the elements in modern chemistry. Soon, he had a bow of elements arranged by...If you want to get a full essay, fix it on our website: Ordercustompaper.com
