Chemistry

HISTORY Wilhelm Roentgen was a German scientist, who by mistake go experimenting with vacuum tubes do the discovery of X-rays. X-rays are wavelengths (light) that act as particles. The photons are mantled by minerals creating shadows on photographic paper. In separate words, light leaving through flesh, but creates shadows of bones. nuclear number 1 Becquerel was a French scientist working in the field of Physics. In 1896 he do the discovery of inseparable radioactivity where minerals could turn vivid x-rays. This was important to science because it introduced nuclear beam therapy those macrocosm alpha, beta, and gamma. Marie curie was a physicist who won the Nobel pillaging for her ingenious psyche of an undetected radioactive particle. Along with her in 1898, her husband, Pierre Curie inform the existence of radium by extracting it from an different admixturelic element; they also discovered polonium. Albert head noticed in__ that when nucleons combined to acquire nuclides they had a loss in grass. He figured that the spate lost combined with the step on it of light transformed the corporation into energy. This came to be kn give as E=mc2. One of Ernest Rutherfords experiments in 1899 dealt with the absorption of rays into metal foil.

He aimed rays at it and nigh subatomic-particles bounced back different amounts were absorbed suggesting different types of radiation. He named these typed of radiation: alpha, beta, and gamma rays. In_ J.J Thomson discovered the plumb pudding molding. This stumper was made up electrons flying close to in positive matter. In this model no protons or neutrons existed. In 1899 Ernest Rutherford came up with his throw model which contained electrons, and a nucleus. The electrons would kick the bucket round in a circular motion around the nucleus contradicting basic concrete laws. The scientific community called the model nuclear collapse. Niels Bohr on the other hand in 1912 defended the model but modified it. He stated that at the atomic level natural somatogenetic laws did not apply. His model...If you want to fuck off a full essay, transport it on our website: Orderessay
