About five years after J.J. Thomson proposed his atomic model in 1897, Ernest Rutherford developed a new atomic model in 1911. Rutherford's model was based on his gold foil experiment, which demonstrated that atoms have a small, dense nucleus surrounded by orbiting electrons. His findings shifted the understanding of atomic structure, leading to the Rutherford model, which laid the groundwork for later developments in atomic theory.

How many days did it take for Niels Bohr to make the model?
Niels Bohr developed his atomic model over several years in the early 20th century, starting around 1913. It took several years of experimentation, collaboration, and refinement before Bohr arrived at his final model that incorporated quantum theory into the structure of the atom.
Whose geocentric model of the solar system was accepted for 1400 years?
The geocentric model of the solar system, which placed Earth at the center with the celestial bodies moving around it, was developed by the ancient Greek astronomer Ptolemy. This model was widely accepted and used for approximately 1400 years until it was eventually replaced by the heliocentric model proposed by Copernicus.
Picture of the early scientist in atomic theory?
I'm unable to view or access external content such as pictures. However, early scientists in atomic theory include John Dalton, who proposed the atomic theory in the early 19th century, and J.J. Thomson, who discovered the electron in the late 19th century. Other key figures include Ernest Rutherford and Niels Bohr, who made significant contributions to our understanding of the atom.
When and where was the specroscope made?
The spectroscope was first made in Germany by Joseph von Fraunhofer in 1819. 40 years later, a more sophisticated model of the spectroscope was developed by Gustav Robert Kirchhoff and Robert Bunsen.
Which scientist said that different elements are made of different types of atoms?
Thomson

What is the Thomson contribution to the atom model theory?
J J Thomson was the first person to suggest the theory of the atom containing positive and negative particles, and demonstrated the latter which he called electrons. He experimented with cathode ray tubes to show how electron beams were deflected by magnetic forces. He also showed the hydrogen atom has one electron. He worked at Cambridge EnglandHis atomic theory identified that electrons inside an atom could show, meaning that atoms were not invisible.Thomson suggested that the model of an atom as a sphere of positively charged matter with negatively charged electrons surrounding them. He stated that electrons were positioned by electrostatic forces.After the discovery of the electron and proton as subatomic particles J.J. Thomson had started to discover atomic theory that gives complete explanation of atomic structure.According to Thomson protons are embed in the atoms like a water melon and electrons are present in atoms to make the atom electrically neutral.his discovered atomic theory was not able to explain the atomic structure properlyRead more: What_was_JJ_Thomson's_major_contributions_to_the_atomic_theory. Awarded Nobel Prize in 1906.AnswerJ.J Thomson view of atom was on the electrons, like "raisins," are stuck into a lump of protons, like "dough," in a "plum pudding" atom.This is the "plum pudding" atom
