Which scientists proposed the nuclear a tomic model with a centrally located positively charged nucleus based on the result of his gold foil experiment?
Ernest Rutherford published a paper proposing the planetary model in 1911. This followed the experiment performed by Hans Geiger and Ernest Marsden under the direction of Rutherford in 1909, where gold foil was bombarded with alpha particles .
What else can I help you with?
What did thomson's cathode-ray tube experiment help scientists learn?
Thomson's cathode-ray tube experiment helped scientists understand that electrons are negatively charged particles within atoms. This experiment contributed to the development of the plum pudding model of the atom, which proposed that electrons are embedded in a positively charged sphere within the atom.
Which of the following scientists proposed the theories of relativity?
Albert Einstein proposed the theories of relativity.
What scientist described the atom as mostly empty space with small positively charged nucleus because of the positive charges of the protons was?
This description of the atom was proposed by Ernest Rutherford through his famous gold foil experiment in 1909. Rutherford's findings led to the development of the nuclear model of the atom, where electrons orbit a dense, positively charged nucleus at the center.
The scattering of alpha particles by thin metal foils established that?
the atom has a dense, positively charged nucleus at its center. This experiment, conducted by Ernest Rutherford, provided evidence for the nuclear model of the atom and disproved the plum pudding model proposed by J.J. Thomson.
Who is the scientist who proposed that light is a wave?
Thomas Young is the scientist who proposed in 1801 that light is a wave, using his double-slit experiment to support this theory.
What did thomson's cathode-ray tube experiment help scientists learn?
Thomson's cathode-ray tube experiment helped scientists understand that electrons are negatively charged particles within atoms. This experiment contributed to the development of the plum pudding model of the atom, which proposed that electrons are embedded in a positively charged sphere within the atom.
What is the name of the scientists who first proposed that atoms have a nucleus?
Ernest Rutherford, following the "gold foil" experiment.
What is the name given to a set of controlled observations that test a proposed explanation?
A set of controlled observations that test a proposed explanation are known as an experiment. The proposed explanation is known as the hypothesis of the experiment.
Which of the following scientists proposed the theories of relativity?
Albert Einstein proposed the theories of relativity.
Who are the scientists who proposed the theory of continental drift?
alfred wegner
What scientist described the atom as mostly empty space with small positively charged nucleus because of the positive charges of the protons was?
This description of the atom was proposed by Ernest Rutherford through his famous gold foil experiment in 1909. Rutherford's findings led to the development of the nuclear model of the atom, where electrons orbit a dense, positively charged nucleus at the center.
Who discovered that protons exIst in the nucleus?
Ernest Rutherford is credited with the discovery that protons exist in the nucleus of an atom through his gold foil experiment in 1911. He proposed that atoms have a small, positively charged nucleus where most of the mass is concentrated.
How did the results on j j thomsons experiments change how scientists thought about atoms?
J.J. Thomson's experiments with cathode rays helped to discover the existence of the electron, challenging the prevailing notion that atoms were indivisible. This led to the development of the plum pudding model of the atom, which proposed that electrons were embedded in a positively charged sphere. Thomson's work paved the way for a new understanding of the structure of atoms as composed of subatomic particles.
What scientists first proposed that the sun is the center of the solar system?
galileo
With what scientists proposed the meteorite impact hypothesis to explain the extinction of the?
Dinosaur?
Scientists proposed that earth's landforms are constanly moving?
James Hutton
What did Ernest Rutherford find in his gold experiment?
Ernest Rutherford, through his famous gold foil experiment, discovered that atoms have a small, positively charged nucleus at their center with electrons orbiting around it. This led to the development of the nuclear model of the atom and overturned the previous plum pudding model proposed by J.J. Thomson.
