Who is credited with the development of the the atomic theory?
John Dalton first pursued research into atomic theory. He was the first person to propose the existence of the atomic structure.
Who developed the first scientific atomic theory?
john dalton developed the atomic theory , which he published in 1803
What particles contribute to the charge of an atom?
In terms of atomic theory the protons and electroncs contribute the charge to an atom. In terms of quantum theory electrons are a type of lepton and protons are composed of quarks. So quarks and leptons contribute nuclear charge.
How did Nagaoka contribute to the atomic theory?
He contriubuted to modern science with his model for atomic theory which he described was similar to the rings of saturn and he descibed that in his model of atomic theory. Hantaro Nagaoka was a great man and and he contributed alot of tings to modern science i cant name them all but he contributed alot of things to modern science
When would scientists need to change a theory?
Scientists had made observations that did not fit exactly with Dalton's theory. Scientists changed the atomic theory to include this new knowledge. While the modern atomic theory is based on Dalton's theory, it is also very different.
Robert A. Millikans contributions to the atomic theory?
Robert A. Millikan was the first to determine the electrical charge of the electron.
What was Robert Millikan's theory?
Robert Millikan measured the electrical charge of the electron.
What did Millikan contribute to atomic theory?
He discovered that the weight of an electron is 1836 times smaller than that of a hydrogen atom (atomis mass of 1)
Who conducted experiments to determine the quantity of charge caried by an electron?
Robert A. Millikan conducted these experiments. His discoveries are instrumental to atomic and particle theory.
What did leucippus contribute to the atomic model or theory?
he did not develop anything regarding the 'atomic theory' for he was against that theory.
What is the millikans contribution to the atom model theory?
Robert Millikan did his experiment by bombarding a thin sheet of beryllium with an alpha particle newtest3
Robert millikan's major contributions to the atomic theory?
Millikan: He discovered that the weight of an electron is 1840 times smaller than a hydrogen atom (atomis mass of 1) Thomson: Thomson was the first person to suggest the theory of the atom containing positive and negative particles, and demonstrated the latter which called electrons
