Which statement reflects the results of Rutherford’s gold foil experiments? –Almost all of the alpha particles passed directly through the foil.The gold foil experiment led to the conclusion that each atom in the foil was composed mostly of empty space because most alpha particles directed at the foil..Thomson’s model of the atom as a uniformly distributed substance. Because only very few of the alpha particles in his beam were scattered by large angles after striking the gold foil while most passed completely through, Rutherford knew that the gold atom’s mass must be concentrated in a tiny dense nucleus.
Which conclusions were drawn from the results of the gold foil experiment?
The gold foil experiment led to the conclusion that each atom in the foil was composed mostly of empty space because most alpha particles directed at the foil..
How did Rutherford confirm the results of the gold experiment?
Thomson’s model of the atom as a uniformly distributed substance. Because only very few of the alpha particles in his beam were scattered by large angles after striking the gold foil while most passed completely through, Rutherford knew that the gold atom’s mass must be concentrated in a tiny dense nucleus.

What did Rutherford’s gold foil experiment prove quizlet?
In the gold foil experiment, since some of the positive alpha particles were substantially deflected, what did Rutherford conclude? He concluded that there must be something inside an atom for the alpha particles to bounce off, that must be small, dense, and positively charged.
What were the observed results of the gold foil experiment?
The gold foil experiment results in the Rutherford model, where the atom is composed of a positively charged nucleus surrounded by negatively charged electrons. The Ernest Rutherford model of the atom contains a central positively charged nucleus surrounded by electrons. The atom is still mostly empty space.
What are the conclusions of Rutherford gold foil experiment?
The conclusion of the gold foil experiment are, In an atom, the nucleus is the positively charged centre. The nucleus contains almost all of a mass of the atom. Electrons follow circular paths around the nucleus.
What are the conclusions made by Rutherford?
The observations made by Rutherford led him to conclude that: A major fraction of the α-particles bombarded towards the gold sheet passed through it without any deflection, and hence most of the space in an atom is empty.

What did Rutherford discover in his experiment?
What did Ernest Rutherford discover about the atom? Ernest Rutherford found that the atom is mostly empty space, with nearly all of its mass concentrated in a tiny central nucleus. The nucleus is positively charged and surrounded at a great distance by the negatively charged electrons.
Which conclusion could be made from Ernest Rutherford’s gold foil experiment quizlet?
What conclusion could be made from Ernest Rutherford’s gold foil experiment? :Atoms are made up of mostly empty space.
What are the observations of Rutherford gold foil experiment?
His two primary observations were: Most α particles passed straight through the gold foil, which showed that atoms are mostly empty space. Some of the α particles were deflected at various angles, and sometimes even back at the radioactive source.
What explanation did Rutherford suggest to explain these observed results?
The only explanation, Rutherford suggested in 1911, was that the alpha particles were being scattered by a large amount of positive charge concentrated in a very small space at the center of the gold atom.

What were the three major observations Rutherford made in the gold foil experiment?
1)Most of the Alpha particles pass Straight Through the gold foil without any deflection from their original path . 2)A few Alpha particles are deflected through small angle and a few are deflected through larger angle.
Why did Rutherford use gold foil?
For the scattering experiment, Rutherford wanted a metal sheet which could be as thin as possible. Gold is the most malleable of all known metals. It can easily be converted into very thin sheets. Hence, Rutherford selected a gold foil for his alpha-ray scattering experiment.
