Millikan's oil drop experiment, conducted in 1909, provided the first precise measurement of the elementary electric charge. By observing the behavior of tiny oil droplets in an electric field, Millikan demonstrated that electric charge is quantized, existing in discrete units. This experiment bolstered the atomic theory by confirming that atoms contain charged particles, specifically electrons, and helped to solidify the understanding of atomic structure, leading to advancements in quantum physics. Consequently, it shifted scientists' views by establishing that atoms are not indivisible but composed of smaller charged components.

How did Rutherford's experiment shape our current model of the atom?
In 1910, a physicist from New Zealand, Ernest Rutherford performed an experiment known as Rutherfordâ??s gold foil experiment. After Rutherford's theory, scientists began to consider that the atom is not a single particle, but it is made up of very smaller subatomic particles.
Why have scientists revised the a atomic model many times?
they could discover a new atom and it would change
How have scientists like JJ Thomson Ernest Rutherford and Niels Bohr helped to change and improve your scientific understanding of the atom?
Scientists like JJ Thomson, Ernest Rutherford, and Niels Bohr were pioneers in advancing our understanding of the atom. Thomson discovered the electron and proposed the plum pudding model, Rutherford conducted the gold foil experiment leading to the discovery of the atomic nucleus, and Bohr introduced the idea of quantized electron energy levels and the planetary model of the atom. Together, their contributions laid the foundation for modern atomic theory and our understanding of the structure of atoms.
How did Robert Millikan's oil drop experiment change scientists' view of the atom?
Robert Millikan's oil drop experiment, conducted in 1909, provided the first accurate measurement of the charge of the electron. By observing the behavior of tiny oil droplets in an electric field, Millikan demonstrated that electric charge is quantized, meaning it exists in discrete amounts. This finding reinforced the idea of subatomic particles and contributed to the understanding of atomic structure, leading scientists to recognize that atoms are composed of smaller charged particles. Millikan's work helped shift the scientific perspective toward a more nuanced model of the atom, incorporating the existence of electrons and their quantized nature.
What did Rutherford's gold foil experiment tell them about the atom?
It told them that the atom was mostly empty space.

The gold-foil experiment led scientists to conclude that an atom's volume is mainly unoccupied.
What might happen to cause scientists to change the model of an atom?
they might actually see an atom.

How did Rutherford's experiment change scientists' previous idea of the atom?
Rutherford shot radiation at a foil of metal, only to find that it went straight through most of the time. This lead him to theorize that the atom consisted of a dense nucleus that had most of the mass, but was much smaller than the atom itself. This hypothesis turned out to be correct.
How did Rutherford's experiment shape our current model of the atom?
In 1910, a physicist from New Zealand, Ernest Rutherford performed an experiment known as Rutherfordâ??s gold foil experiment. After Rutherford's theory, scientists began to consider that the atom is not a single particle, but it is made up of very smaller subatomic particles.
Scientists who performed the gold foil experiment?
Ernest Rutherford and his team conducted the gold foil experiment in 1909 at the University of Manchester. The experiment led to the discovery of the atomic nucleus and paved the way for our understanding of the structure of the atom.
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.
How did thompsons experiment change daltons atomic model?
thomas discovered that the atom contained smaller particals called electrons
How did the Thomson's experiment change Dalton's atomic model?

What is a scentence for the word ATOM?

Who discovered the nuclear atom?
The nuclear atom was discovered by Ernest Rutherford. He did it with a gold foil experiment.
Which of the following statements about the atom did Rutherfords experiment support?
Rutherford's experiment supported the statement that the atom has a nucleus, which contains the majority of the atom's mass and is positively charged. It also indicated that the nucleus is small and dense compared to the overall size of the atom.
