In Rutherford's gold foil experiment Rutherford concluded that the atom is mostly empty space with a small massive positively charged center because most of the electrons passed through but a few were wildly deflected.

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.
When Rutherford found that some of the alpha particles fired at the gold foil were widely deflected he concluded that?
He concluded that most of the mass of the mass of the atom is concentrated at a single place at the centre of atom. He named this place as the nucleus.
What is Rutherford's experiment with gold foil and alpha particles?
The initial discovery of "Rutherford Scattering" was made by Hans Geiger and Ernest Marsden in 1909 when they performed the gold foil experiment under the direction of Rutherford, in which they fired a beam of alpha particles (helium nuclei) at layers of gold leaf only a few atoms thick. The intriguing results showed that around 1 in 8000 alpha particles were deflected by very large angles (over 90°), while the rest passed straight through with little or no deflection. From this, Rutherford concluded that the majority of the mass was concentrated in a minute, positively charged region (the nucleus) surrounded by electrons. When a (positive) alpha particle approached sufficiently close to the nucleus, it was repelled strongly enough to rebound at high angles. The small size of the nucleus explained the small number of alpha particles that were repelled in this way.
Who concluded that particles can have some of the properties of light?

How did Rutherford explain the results of his gold foil experiment?
Rutherford made the following conclusions:Since most of the alpha particles passed straight through the gold foil without any deflection, most of the space within the atoms is empty.Since some of the alpha particles (which are big in size) were deflected by large angles or bounced backwards, they must have approached some positively charged region responsible for the deflection. This positively charged region is now called the nucleus.As very few alpha particles undergone the deflection, it was concluded that the volume occupied by the central region ( nucleus ) is very small.Since alpha particles which are relatively denser, were deflected by the central volume of charge, it shows that almost the complete mass of the atom must be within the central volume.
Rutherford concluded from his calculations that the volume of an atom is?
its mostly empty space
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.
When Rutherford found that some of the alpha particles fired at the gold foil were widely deflected he concluded that?
He concluded that most of the mass of the mass of the atom is concentrated at a single place at the centre of atom. He named this place as the nucleus.
What did Rutherford have to say about the structure of the atom?
Rutherford concluded that they have a nucleus,a central positive nucleus surrounded by negative orbiting electrons.
Did John Dalton or John Joseph Thomson or Ernest Rutherford or James Chadwick concluded that the cathode ray consists of electrons?
John Joseph Thomson
What was the conclusion of Rutherford's gold foil experiment in terms of an atom's mass and volume?
Rutherford found that when when he aimed alpha particles at a thin sheet of gold foil, that some of the particles were deflecteted and didn't go straight through the foil. The reason for this turned out the be that they ran into the nucleus. Most of the particles did go straight through, so Rutherford concluded that the atom was mostly empty space. He also concluded that the center of the atom contained the nucleus and had positively charged particles he called protons.
What was the Ernest Rutherford's experiment?
Rutherford, Geiger and Marsden observed that a beam of alpha particles is deflected on a gold foil. They concluded that this effect is due to a positive entity in the atom. And they discovered the atomic nucleus, separate from electrons and the model of Thomson become obsolete.
What is the nuclear models of the atoms?
It is called the "nuclear model" Rutherford concluded that 1. Atom is mostly empty space 2. Atom has a nucleus at its center 3. Electrons surround the nucleus
What is the structure of the atom as proposed by Rutherford?
Before Rutherford, scientists assumed that the atom was a single particle. Rutherford presented his revolutionary, physical atomic model that suggested an atom consists of a central charge (the term 'nucleus' was coined after Rutherford's model was presented) that is surrounded, presumably, by a cloud of orbiting electrons. He showed that most of an atom's mass was located in the atom's nucleus. Rutherford's model was later improved upon by Niels Bohr, father of the Bohr-model. Rutherford made no connection to an element's atomic number and the number of protons within an atom's nucleus; however, his atomic model paved the way for the discovery of this correlation only a couple years after his model was designed.
Who discover the proton and neutron?
The gradual realization of protons was made through the work of physicists like Ernest Rutherford and Eugen Goldstein in the 1910s. James Chadwick concluded the existence of neutrons in 1932 to explain a new type of radiation.
What did Rutherford infer as a result of his observations?
Rutherford Discovered Many key factors of the atom. Especially about Protons and Electrons. He Did Not Know about neutrons. He Concluded That The atoms electron cloud was positive and electron floated around it like chocolate chips in a cookie.
How do you use word concluded in sentence?
You can use the word "concluded" in a sentence to indicate that something has been determined or reached a decision after considering all relevant information. For example, "After reviewing all the evidence, the jury concluded that the defendant was guilty."
