Albert Einstein (1879-1955) was a German-born theoretical physicist and winner of the 1921 Nobel Prize in Physics. Einstein influenced the beginning of the Manhattan Project. In collaboration with Leo Szilard, Einstein wrote a letter to President Roosevelt in 1939.

Contribution to Atomic Theory. He developed the periodic table. He organized the elements into a table according to their atomic weights. When the elements were arranged in ascending order in their weights, their properties repeated in a pattern. He used the table by a means of predicting new elements as well as just organizing them.

He was elected as a fellow of the Royal Society of London J. J. Thompson Contribution to the science of physics was the justification from physical laws of the previous empirical and chemical concept of the atomic number Henry Moseley Was a philosopher and a promoter of scientific research Niels Bohr

In 1803 John Dalton proposed an "atomic theory" with spherical solid atoms based upon measurable properties of mass.

Karlsruhe and the Question of Atomic Weights. In 1860 Meyer and Mendeleev were among the young chemists attending the first ever international chemistry congress, the Karlsruhe Congress, and both were impressed with Stanislao Cannizzaro’s presentation of Amedeo Avogadro’s hypothesis and the light it shed on the question of atomic weights. For both, writing a textbook proved to be the impetus for.

Atomic Theory. Print; Main. Democritus 0460 bc – 0370 bc. J. Plucker 1859 – 1860. Built one of the first cathode ray tubes. Niels Bohr 1862 – 1962. Discovered a neutral atomic particle using alpha particles with a mass close to a proton, thus the neutron was born! De Broglie 1892 – 1987.

Contribution. Like Boyle, Newton studied gases, and the possibility of atoms existing, and like Boyle, his work was impeded by the church. He proposed a mechanical universe where small solid masses were in motion. In short, he believed that there were little tiny pieces of mass that were ‘swimming’ everywhere.

Ernest Rutherford disproved Thomson’s theory of the atom in 1911 when he showed that atoms are mostly composed of empty space. Rutherford discovered this by firing alpha rays – helium nuclei – at a thin sheet of gold foil. If Thomson’s theory were correct,

Solidified the atomic theory. He proved the existence of atoms with experiments and came to the conclusion that all elements are made of submicroscopic parts called atoms.

John Dalton 1766 – 1794 Dalton contributed to the atomic theory,that matter is composed of the atoms of differing weights combined in simple ratio’s by weight.Dalton was the first to prepare a.

Nov 25, 2019  · Atomic theory is the idea that matter is made up of little units called atoms. When the ancient Greek philosopher Democritus came up with the idea in the 5th century BC, is was originally meant to refer to indivisible units. As of 1897, the British scientist J.J. Thomson discovered that atoms are in fact made up of smaller particles.
