== == 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.

Which discovery led J.J Thomson to improve on John Daltons model of the atom?
An atomic model from John dalton doesn't exist.
Events the led to the discovery of DNA?
Watson and crick and the discovery of the double helix
What was the discovery in the 15th century greatly advanced the progress of science?
the discovery of metals led to tools that lasted longer
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 experiments lead to the discovery of DNA?
Friedrich Miescher performed experiments in the lab at the University of Tubingen in 1868. He experimented with the chemical composition of leukocytes, and these experiments led to the discovery of DNA.
What experimental evidence led Thomson to develop the model of an atom?
The discovery of a negative charged particle - electron - in the atom.
Alpha particles led to what discovery of what?
discovery of the atom's structure
Experiments with cathode rays led to the discovery of which subatomic particle?
Experiments with cathode rays led to the discovery of the electron.
What experiment led to the discovery of the nucleus of an atom?
The gold-foil experiment
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 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.
Do Rutherford's gold foil experiment led to the discovery of the portion of the atom known as the nucleus?
shail = whale to the power of 2
Which experimental discovery led Niels Bohr to revise Rutherford's model of the atom?
Electrons have more energy the farther they are from the nucleus.
Which discovery led J.J Thomson to improve on John Daltons model of the atom?
An atomic model from John dalton doesn't exist.
The scientist whose alpha-particle scattering experiment led him to conclude that the nucleus of an atom contains a dense center of positive charge is?
Rutherford
What scientist's experiment led to the discovery of protons?
Ernest Rutherford's experiment led to the discovery of protons.
What discovery led to the revision of atomic theory from the Democritus' model to John Dalton's model of the atom?
That chemical reactions allowed atoms to be changed and moved.
