BY THE GOLD FOIL EXPERIMENT . IN THAT EXPERIMENT ALMOST ALL THE THE a-particles CROSSED THE GOLD FOIL THUS THE +ve REGION OCCUPIES VERY LESS SPACE.

∙ 11y agoHe fired alpha particles at a thin sheet of gold foil that was surrounded by detectors. Some of the particles went through the gold foil, some defected sharply and some ricocheted directly back at the source of the alpha waves. Rutherford said, " this was as if one had fired a 15 inch gun at tissue paper and the shell bounced right back at you. "
So, the plum pudding model which posited a distributed atom was disproved and Rutherford posited that a dense mass existed at the center of the atom.

∙ 12y agoHe decided upon this conclusion because when he put a thin sheet of foil and got some atomic bullets and fired them at it, most of the bullets just went straight through because there was nothing stopping them. but a few were deflected and so he decided that the bits where the bullets were deflected must hold all the mass of the Atom.

∙ 13y agoHe bombarded a thin metal foil with alpha particles, (helium nuclei) and was astonished to find some of the particles were thrown back towards the source. He concluded that the charged part of the atoms (now called the nucleus) must be a tiny point, so that the alpha particles were getting in very close to a charge concentrated into a tiny space with very high locally concentrated electric fields. He said it was as amazing as firing a cannon ball at a piece of paper and discovering the ball being deflected back at you. (not a real comparison because the atoms in a piece of paper are not as big as cannon balls).

∙ 8y agoErnest Rutherford mostly believed in that it was mostly empty space with positively charged atoms.

Describe Rutherford's Model of the atom?
Rutherford's model of the atom consisted of a positively charged center, known as NUCLEUS, which also contained most of the atom's mass. Around the nucleus orbited the negatively charged electrons.
Who discovered the positive charge of a nucleus?
Ernest Rutherford is the scientist that discovered the positively charged nucleus.
What main feature of Thomson atomic model was charged after Rutherford discoveries?
The main feature of the Thomson atomic model that was challenged after Rutherford's discoveries was the idea that the atom was a uniformly distributed positive charge with negatively charged electrons embedded within, often referred to as the "plum pudding" model. Rutherford's gold foil experiment demonstrated that the positive charge in an atom is concentrated in a small, dense nucleus at the center, leading to the development of the nuclear model of the atom.
What is the difference between the models made by Rutherford and Dalton?
Dalton's atomic model simply stated that all elements were made of tiny atoms, he said nothing about the structure of those atoms. Rutherford proposed that most of the mass of the atom is concentrated in a tiny central nucleus with positive charge.
Is positive charge spread equally over an atom?
No the postive charge is only concentrated in one spot the atom
Who atomic model determined that an atoms positive charge is concentrated in the atoms center?
This is the Rutherford model.
What scientist concluded the nucleus of an atom contains a dense center of positive charge?
Ernest Rutherford concluded that an atom contains a very small, dense center, called a nucleus, with a positive charge as a result of his gold foil experiment.
Which component of the atom is not represented in Rutherford's atomic molecule?
When Rutherford discovered the positive charge in an atom was concentrated in the nucleus, the neutron had yet to be discovered. There are no neutrons in Rutherford's model.
Who is the scientist that discovered the nucleus?
Actually Ruthford discovered the Nucleus
Describe Rutherford's Model of the atom?

What did Rutherford believe was in the center of an atom?
a nucleus with a positive charge
What did Rutherford believe in the center of an atom?
a nucleus with a positive charge
Who discovered the positive charge of a nucleus?
Ernest Rutherford is the scientist that discovered the positively charged nucleus.
Which of the following provided evidence that most of the mass of the atom as well as all of the positive charge is concentrated in a very small core the nucleus?
The scattering of alpha particles by a metal foil.
What main feature of Thomson atomic model was charged after Rutherford discoveries?
The main feature of the Thomson atomic model that was challenged after Rutherford's discoveries was the idea that the atom was a uniformly distributed positive charge with negatively charged electrons embedded within, often referred to as the "plum pudding" model. Rutherford's gold foil experiment demonstrated that the positive charge in an atom is concentrated in a small, dense nucleus at the center, leading to the development of the nuclear model of the atom.
What did Ernest Rutherford's experiment prove?
We should never say that an experiment has proven something. The Rutherford gold foil experiment led to the hypothesis that an atom's positive charge is concentrated in an incredibly small space at the atom's center.
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
