What experiments demonstrated that atoms are mostly empty space?
The alpha particle scattering experiment by Ernest Rutherford (1911) demonstrates that more than 99.9% of an atom contains empty space.
What is the name of the scientists who first proposed that atoms have a nucleus?
Ernest Rutherford, following the "gold foil" experiment.
What scientist said gold foil experiment which proved in early 20th century that atoms had a nucleus?
Ernest Rutherford, a New Zealand-born physicist, conducted the gold foil experiment in the early 20th century. This experiment involved shooting alpha particles at a thin gold foil and observing their scattering patterns. Rutherford's observations led to the conclusion that atoms have a dense, positively-charged nucleus at their center, which eventually formed the basis of the modern atomic model.
What is the contributions of Ernest Rutherford?
Ernest Rutherford deduces the existence the atomic nucleus from alpha particle scattering experiments performed with Hans Geiger and Ernes Marsden.
Who said atoms contain mostly empty space?
Anybody who knows much about atoms and is willing to ignore virtual particles. The credit for actually discovering this should probably go to Rutherford. (Or Rutherford, Geiger, and Marsden ... Geiger and Marsden actually did the experiment in Rutherford's lab, and Rutherford was the one who explained the results.)
Who said atoms were made up of subatomic particles?
Rutherford proved it it from his alpha-particle scattering experiment.
What experiments demonstrated that atoms are mostly empty space?
The alpha particle scattering experiment by Ernest Rutherford (1911) demonstrates that more than 99.9% of an atom contains empty space.
Who discovered that atoms were composed of protons and neutrons?
neutrons were discovered by james chadwick by an experiment which was started by madam curie. protons were discovered by rutherford in his alpha ray scattering experiment
What is the name of the scientists who first proposed that atoms have a nucleus?
Ernest Rutherford, following the "gold foil" experiment.
What did Rutherford discover atoms?
Rutherford by passing interpretation about the famous alpha particle scattering experiment came to the conclusion that the positively charged nucleus is of small size of the order of 10-15 m where as the atom size is of the order of 10-11m

Ernest Rutherford, a New Zealand-born physicist, conducted the gold foil experiment in the early 20th century. This experiment involved shooting alpha particles at a thin gold foil and observing their scattering patterns. Rutherford's observations led to the conclusion that atoms have a dense, positively-charged nucleus at their center, which eventually formed the basis of the modern atomic model.
Which statement is consistent with the results of Rutherford's gold foil experiment?
In Rutherford's gold foil experiment atoms are mostly empty space.
How do we use Rutherford's gold foil experiment today?
The Rutherford gold foil experiment is also known as the Geiger-Marsden experiments. In them, alpha particle scattering was measured, and showed how a large focus was found in such a way as to describe atoms having a dense nucleus. This experiment is not used for much today in any field other than focused particle physics, wherein it is the basis of most other calculations involving how atoms work.
Who is Ernest Rutherford?
Ernest Rutherford was a New Zealand chemist and physicist who became known as the father of nuclear physics. He discovered that atoms have their positive charge concentrated in a very small nucleus and thereby pioneered the Rutherford model, or planetary, model of the atom, through his discovery and interpretation of Rutherford scattering in his gold foil experiment. He was awarded the Nobel Prize in Chemistry in 1908
What were the surprising results of Rutherford's gold-foil experiment?
The most surprising fact about Rutherford's experiment is that some of the atoms bounced backwards while others scattered.
Who discovered that atoms were mostly empty space?
Rutherford, with his gold foil experiment.
Atoms are made of protons neutrons and electrons- was that what the conclusion was with Rutherford's experiment?
yes it was.
