Most of the alpha particles shot at the gold foil went straight through the foil.

How did Ernest Rutherford deduce that he had observed a transmutaion in his cloud chamber?
While studying the passage of high-speed alpha particles (helium nuclei) through water vapor in a cloud chamber, Ernest Rutherford observed some long, thin particle tracks. These tracks matched the ones caused by protons in experiments performed earlier by other scientists.
How did Ernest Rutherford did deduce that he observed a transmutation in his cloud chamber?

What was the Ernest Rutherford's experiment?
Rutherford, Geiger and Marsden observed that a beam of alpha particles is deflected on a gold foil. They concluded that this effect is due to a positive entity in the atom. And they discovered the atomic nucleus, separate from electrons and the model of Thomson become obsolete.
What was Rutherford first experiment?
Rutherford's first experiment was the famous gold foil experiment in 1909. In this experiment, he bombarded a thin gold foil with alpha particles and observed how they scattered. The results led to the discovery of the atomic nucleus and the development of the nuclear model of the atom.
Who said Protons exist?
Ernest Rutherford is credited with discovering that protons exist. In his famous gold foil experiment, Rutherford observed that alpha particles were deflected by the positive charge of the nucleus, leading to the conclusion that the nucleus contains positively charged particles which we now know as protons.

What Rutherford might have observed if he had bombarded copper metal instead of gold with alpha particles?
Rutherford would likely have observed most alpha particles passing straight through the copper metal due to the low atomic weight and higher density of copper compared to gold. Occasionally, he may have observed some deflections at large angles, indicating interactions with the positively charged nucleus. Overall, the majority of alpha particles would have traversed the copper without much scattering.
What did Rutherford observe when he fired alpha partices at pieces of thin metal foil?
Rutherford observed that most alpha particles passed straight through the foil, but a small percentage were deflected at large angles. This led him to conclude that the atom has a small, dense nucleus surrounded by mostly empty space.
What scientist concluded the nucleus of an atom contains a dense center of positive charge?
Ernest Rutherford is the scientist who concluded that the nucleus of an atom contains a dense center of positive charge. This conclusion was based on the results of his famous gold foil experiment in which he observed the scattering of alpha particles. Rutherford's discovery revolutionized the understanding of atomic structure and laid the foundation for the development of the modern atomic model.
Who was the scientist responsible for discovering the nucleus of the atom?
Ernest Rutherford is credited with discovering the nucleus of the atom through his gold foil experiment in 1909. He observed that most of the particles passed through the foil, suggesting that the atom is mostly empty space with a concentrated positive charge at the center, which he called the nucleus.
What was a testable idea that Ernest Rutherford developed in his experiments?
Ernest Rutherford's testable idea was that atoms have a small, positively charged nucleus at their center. He conducted the famous gold foil experiment, in which he observed the scattering of alpha particles, to support this concept. This experiment provided evidence for the existence of a dense nucleus within atoms.
What technology helped Ernest Rutherford discover the atom?
Ernest Rutherford used the technology of radioactivity and conducted the famous gold foil experiment to discover the structure of the atom. By directing alpha particles at a thin gold foil, he observed how they were deflected, which led to the understanding that atoms have a small, positively charged nucleus at their center.
