Complicate and new theories are continuously controversial; but this controverse is the source of progress in knowledge.

What were The targets used in the alpha particle atomic experiments in the early 1900's?
Gold foil was typically used as the target in alpha particle atomic experiments in the early 1900s. This was famously utilized by Ernest Rutherford in his gold foil experiment to study the structure of the atom.
How did Albert Einstein make the atom?
Albert Einstein did not make the atom. He was a theoretical physicist who made significant contributions to our understanding of the atom through his work on the theory of relativity and his explanation of the photoelectric effect. He did not create or discover the atom itself.
Who scientists are involved in the development of atomic theory?
Some key scientists involved in the development of atomic theory include John Dalton, who proposed the atomic theory in the early 19th century based on the idea of indivisible particles; J.J. Thomson, who discovered the electron in the late 19th century; and Niels Bohr, who proposed a model of the atom with quantized electron orbits in the early 20th century.
Who are the scientist involve in the atomic theory?
Some of the key scientists involved in the development of atomic theory include John Dalton, who proposed the atomic theory in the early 19th century, J.J. Thomson, who discovered the electron, Ernest Rutherford, known for his gold foil experiment that led to the discovery of the nucleus, and Niels Bohr, who developed the planetary model of the atom.
What scientist thought that an atom was the smallest particle in the universe?
John Dalton, an English scientist, proposed that atoms were the smallest indivisible particles in the universe in the early 19th century. His atomic theory laid the foundation for modern chemistry.
Why was the theory of the atom so controversial back in the early 1900's?
Complicate and new theories are continuously controversial; but this controverse is the source of progress in knowledge.
Rutherford said that almost all the mass of an atom is located in its what?
Rutherford discovered in the early 1900s that most of an atom's mass is located in its nucleus.
What did early atomic theory accomplish?
it started scientific thought about the structure of the atom
What did the early atomic theory accomplished?
it started scientific thought about the structure of the atom
Who developed the basic concept of the atom?
John Dalton was the first person to propose the idea of the atom as the smallest particle in 1803. However, equipment needed to prove the theory was not available until the late 1900s.
What scientist did not have experimental evidence to support his theory of the atom?
John Dalton did not have experimental evidence to support his theory of the atom when he proposed it in the early 19th century. His atomic theory was based on observational patterns rather than direct experimental data.
Who did not have experimental evidence to support his theory of the atom?
John Dalton did not have experimental evidence to support his theory of the atom when he first proposed it in the early 19th century. His model was based on a philosophical approach rather than direct experimental observations.
When was the Electron Cloud theory discovered?
The Electron Cloud theory was proposed in the early 20th century, around the 1920s. It was developed as an improvement to the Bohr model of the atom to better describe the behavior of electrons within an atom.
What did the early theory accomplish?
it started scientific thought about the structure of the atom
When John Dalton date of discovery?
John Dalton discovered the atom in 1803. He didn't really discover the atom. He developed a theory of matter that involved atoms. Atoms were proved to exist later.
What were The targets used in the alpha particle atomic experiments in the early 1900's?
Gold foil was typically used as the target in alpha particle atomic experiments in the early 1900s. This was famously utilized by Ernest Rutherford in his gold foil experiment to study the structure of the atom.
Which came first the theory of natural selection or the theory of relativity or the heliocentric theory or the theory of the the hydrogen atom?
In the following order: Heliocentric theory of the solar system (Aristarchus of Samos, 270 BCE) Natural Selection (Darwinian evolution, 1858) Theory of the hydrogen atom (as a small negatively charged particle inside a larger positively charged particle, 1904, the plum pudding model) Theory of relativity (special relativity, 1905) Theory of relativity (general relativity's initial paper on the acceleration of objects within the framework of special relativity, 1907) Theory of the hydrogen atom (as a small particle orbiting the atomic nucleus, 1909, the Rutherford or Planetary model) Theory of the hydrogen atom (as an "electron cloud" surrounding the atomic nucleus, 1913, the quantum mechanical or Bohr model) Theory of relativity (general relativity and its ability to warp space-time, 1915) So heliocentrism was, by about two millenia, the first. Relativity and the model of the hydrogen atom are intricately intertwined, so which came first depends on what you mean specifically.
