== == Atoms were inferred to exist from the observation of "Brownian motion," which is the jittering of dust particles in air or water or some medium as seen through a microscope. The jitter is supposed to be caused by random collisions of atoms or molecules with the dust particles. If the medium were not composed of particles but were a smooth creamy substance without lumps, there would be nothing to make the dust particles jitter.

What did Rutherford contribute to the study of science?
After Rutherford's discovery(Planetary Model), scientists started to realize that the atom is not ultimately a single particle, but is made up of far smaller subatomic particles. Following it research was done to figure out the exact atomic structure which led to Rutherford's gold foil experiment. They eventually discovered that atoms have a positively-charged nucleus in the center. Since electrons were found to be even smaller, this meant that the atom consists of mostly empty space.
The gold-foil experiment led scientists to conclude that an atom's?
The gold-foil experiment led scientists to conclude that an atom's volume is mainly unoccupied.
What was the discovery in the 15th century greatly advanced the progress of science?
the discovery of metals led to tools that lasted longer
What would be the most appropriate to paraphrase?
Events that led to Edward Jenner's discovery of the smallpox vaccine.(APEX)
What did chadwhicks experiment kead to the discovery of?
Chadwick's experiment led to the discovery of the neutron, which is a subatomic particle with no charge located in the nucleus of an atom. This discovery helped to further our understanding of atomic structure and the composition of matter.
Alpha particles led to what discovery of what?
discovery of the atom's structure
Who did the alpha particle scattering experiment?
The alpha particle scattering experiment was conducted by Ernest Rutherford and his team in 1909 at the University of Manchester. This experiment led to the discovery of the atomic nucleus and revolutionized our understanding of the structure of the atom.
What discovery was J.J. Thomson noted for?
J.J. Thomson is noted for discovering the electron, a fundamental particle found in all atoms. This discovery led to the development of the plum pudding model of the atom and revolutionized our understanding of atomic structure. Thomson's work laid the foundation for future advancements in the field of particle physics.
What Led to the discovery of the nucleus?
Alpha particle ie doubly ionized helium atom scattering by the gold foil experiment formed the basis for the discovery of nucleus. The experiment was done by Marsden and Geiger but the experimental observation was commented and final conclusion derived by Rutherford.
What jj Thomson discover?
J.J. Thomson discovered the electron, a subatomic particle found in all atoms. This discovery led to his development of the plum pudding model of the atom, which revolutionized our understanding of atomic structure.
How did chadwick use the results of his experiment to come up with his theory?
Chadwick's experiment on the deflection of alpha particles by a thin sheet of beryllium led to the discovery of the neutron, as the neutral particle responsible for this deflection. Based on his results, Chadwick proposed that the atom had a neutral particle in its nucleus, now known as the neutron, which explained the missing mass in atoms. This led to the development of the neutron theory of the atomic nucleus.
Atom theory JJ thomas?
J.J. Thomson's atom theory, proposed in the late 19th century, centered around the idea that atoms were composed of smaller subatomic particles. His famous experiment with the cathode ray tube led to the discovery of the electron, a negatively charged particle within the atom. This theory revolutionized the scientific understanding of atomic structure and laid the foundation for further research into the field of particle physics.
What does Rousseau think about the instition of property?
He believed that the discovery of private property was the start of a long journey down a bad path. he thought that the discovery of private property led to scarcity which led to the need for man to develop reason, reason allowed man to perceive the differences between men, this perception led to the perversion of self-love into vanity, which is the reason for inequality and misery in today's society.
What did Rutherford's backward deflection of alpha particle give evidence of an atom's?
Rutherford's backward deflection of alpha particles in the gold foil experiment provided evidence of an atom's nucleus. The deflection indicated that the majority of an atom's mass and positive charge is concentrated in a small, dense nucleus at its center, with electrons orbiting around it. This discovery led to the development of the nuclear model of the atom.
Rutherford's experiments led to the discovery of the?
Rutherford's experiments led to the discovery of the atomic nucleus. Through his gold foil experiment, he found that atoms have a small, dense, positively charged nucleus at their center and that the rest of the atom is mostly empty space. This discovery revolutionized our understanding of atomic structure.
Do Rutherford's gold foil experiment led to the discovery of the portion of the atom known as the nucleus?
