What conclusion about the atom came from Ernest Rutherfords famous gold foil experiment?
Wiki User
∙ 14y ago
The conclusions were that the nucleus in an atom must:-
(1) Be positive as it repelled the positive alpha-particles
(2) Have a high mass, as the deflections were massive
(3) Be very small as only a few of the particles were deflected

What scientist said most of the mass of the atom is in tiny dense positively charged nucleus?
Ernest Rutherford suggested that most of the mass of the atom is located in the nucleus. He came to this conclusion after finding the results on his famous gold foil experiment. This is where he fired radio active particles through very thin metal foils, and detected them using screens covered in zinc sulphide.
What year did Rutherford do his experiment?
The Geiger-Marsden experiment, which is also called the gold foil experiment or the Rutherford experiment, was conducted by Hans Geiger and Ernest Marsden in 1909, under Earnest Rutherford's direction. You need a link to the Wikipedia post on this ground-breaking experiment, and we've got one for you.
Did Ernest Rutherfords results fit with J.J Thomsons view of the atom?
Thomsons model is sometimes called the plum pudding model as he envisaged a soup of positive charge with negative charges, by then already called electrons swimming round. He came up with this idea in 1904."the atoms of the elements consist of a number of negatively electrified corpuscles enclosed in a sphere of uniform positive electrification"Rutherford following on from the famous scattering experiment with gold foil and alpha particles proposed that the positive charge was concentrated in a central nucleus.
Who discovered that an atom is mostly empty space?
Rutherford's Experiment In this expt, Alpha particles (Double positive charged helium atom) were bombarded on a thin gold foil. Observation:- 1) Most of the rays passed straight through it without any deflection...(Answer to ur question) 2) Some rays were deflected through an small angle giving the sense of presence of Electrones 3) 1 out of 20000 rays was was deflected right back through the same path ( Nucleus )
Briefly describe Rutherford's experiment?
The Gold Foil Expirament-Rutherford A line of photons were shot through a thin piece of gold, and rutharford theorized that they should pass through. However some passed through while others deflected and some reflected backwards. It gave proof that atoms have a nucleus
How did Ernest Rutherford influence society?
Ernest Rutherford influenced society by discovering the nucleus and protons. He and his student performed a famous gold foil experiment and came to a conclusion of finding nucleus. He also discovered the protons by doing another experiment.
How did Ernest Rutherford's gold foil experiment change the model of the atom?
After that famous experiment, it was realized that atoms were mostly empty space.
What was ernis rutherfords famous quote?
he had a hippo
What was the significance of Rutherfords work?
Ernest Rutherford's famous "gold foil" experiment changed the way we though of atomic structure. His demonstration proved that atoms have a small, dense nucleus which contains protons and neutrons. The electrons were shown to be outside the nucleus. Prior to this, we thought atoms had a consistent structure throughout, like soup or pudding.
What is one famous event using nuclear chemistry?
Ernest Rutherford, with students Ernest Marsdenand Hans Geiger, in the 'gold foil' experiment, demonstrated the existence of the atomic nucleus.

Who was the first scientist to propose that atoms contained a lot of empty space?
Ernest Rutherford proved it with his famous gold foil experiment.

What results led to Rutherfords famous conclusion?
In early work he discovered the concept of radioactive half life, proved that radioactivity involved the transmutation of one chemical element to another, and also differentiated and named alpha and beta radiation. He was awarded the Nobel Prize in Chemistry in 1908 "for his investigations into the disintegration of the elements, and the chemistry of radioactive substances". Rutherford performed his most famous work after he received this prize. In 1911, he postulated that atoms have their positive charge concentrated in a very small nucleus, nd thereby pioneered the Rutherford model, or planetary, model of theatom, through his discovery and interpretation of Rutherford scattering in his gold foil experiment. He is widely credited with first splitting the atom in 1917, and leading thefirst experiment to "split the nucleus" in a controlled manner by two students under his direction, John Cockcroft and Ernest Walton in 1932.
