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.

How was it proved that the whole mass of an atom is located at its center?
the answer of this question is Rutherford experiment
As of the 1990's scientist have proved the existence of how many states of matter?
2
How can you find the conclusion for how salty does the sea have to be for an egg to float?
yes i proved my hypothesis correct. for my experiment to be correct it relied heavily on the density of the salt in the water
What important discovery did Ernest Rutherford make?
He found that the atom was made up of mostly empty space.
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 )
Who proved the existence of a positively charged nucleus by his experiment with gold foil?
Ernest Rutherford
Rutherford propose center of the atom was negatively charged nucleus?
true but his experiment proved him wrong :)
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.
Causation can be proved by using an?
experiment.
Who proved materials needed oxygen to burn?
Antoine-Laurent Lavoisier proved it in France in the late 18th century. I'm not sure about any of the specific experiments he used to prove it, but you can go here if you want to read about one experiment at the link below:
All cell stay alive by?
All cells stay alive due to the presence of nucleus. Once nucleus removed, the cell cannot sustain. It has been proved by an experiment on an amoeba cell. The nucleus is the main centre which controls all cell activities.
Ernest Rutherford's contribution to the atomic structure due to the gold foil experiment?
Ernest did an experiment where he shot alpha particles into a gold foil that proved the concept of a nuclear atom, that is an atom with a nucleus made of protons and neutrons and have electrons moving around the nucleus in some way. His experiment did not show the position of electrons or energy levels or even how they moved.
How can finding out that a hypothesis is not correct be useful for scientists?
It's not that it's not correct, it was that the experiment proved it wrong. And it is helpful because it tells the scientist that their idea was incorrect do to speak and that the experiment proved it. You can still write a very good report if the hypothesis was proven wrong
Ruthford thoeorized that's an atom is?
no i belive he did the gold foil experiment which proved the existence of the nucleus, he fired protons at an atom and 1 in every 30,000 bounced back.
How did Rutherford's alpha scattering experiment show that Thomson's plum pudding model of the atom incorrect?
Rutherfords experiment proved the existence of a nucleus as some alpha particles "bounced back" from the gold foil sample . Thomson model did not involve a nucleus and predicted just a slight deflection or none at all.
What is significant about Ernest Rutherford?
Rutherford came up with the basic structure of an atom using his gold foil experiment. He shot alpha particles(hydrogen nuclei) at a peice of gold foil and watched the results. He found from this experiment that the atom contains a dense, positively charged nucleus, negative particles in "electron clouds" and is made up of mostly empty space.
What did oparin the scientist proved?
* He proved nothing, but he did say God made the earth.
