Who provided evidence for the existence of the nucleus in an atom?
Ernest Rutherford
Who provided evidence for the existence of a nucleus in an atom?
Ernest Rutherford
What did Ruthford's Gold Foil Experiment provide evidence for?
Rutherford's Gold Foil Experiment provided evidence for the existence of a small, positively charged nucleus at the center of the atom. This discovery led to the development of the nuclear model of the atom and overturned the previous plum pudding model.
What did Rutherford's backward deflection of alpha particle give evidence of an atom's?
Rutherford's backward deflection of alpha particles in the gold foil experiment provided evidence of an atom's nucleus. The deflection indicated that the majority of an atom's mass and positive charge is concentrated in a small, dense nucleus at its center, with electrons orbiting around it. This discovery led to the development of the nuclear model of the atom.
Who was the first scientist to provide evidence that an atom has a nucleus?
Neil Bohr
Who provided evidence for the neutron in an atom?
Ernest Rutherford predicted the nucleus in 1920, 12 years later his assistant James Chadwick found and confirmed it.
What did Sir Ernest Rutherford invent?
Ernest Rutherford discovered that the nucleus of an atom has a positive charge and discovered the evidence to show the electron field surrounding the nucleus in an atom.
Rutherford's gold foil experiment provided evidence for what?
In 1911, Rutherford decided to experiment using what was the current theory of atomic structure at the time. Based on his results, he proposed a new theory; that the majority of the atom is empty space, and that all of the positive and most of the mass are contained in a small central region within the atom, which became later known as the nucleus.
Is there one protons and nucleus in atom?
Yes, all atoms have a nucleus! The Nucleus is the part of the atom which holds the Protons and Neutrons, the Electrons orbit the "atomic nucleus". The atomic nucleus is different to the nucleus of a cell, which holds genetic information and allows the cell to operate. Answer above provided by Runehally16.
Why is Indirect evidence important in the study structure of the atom?
The atom is far too small to ever be examined directly. The diameter of a typical nucleus is only about 1/100,000 of the diameter of the entire atom and if an atom were magnified until it was as large as a football stadium, the nucleus would be about the size of a grape. Nearly all evidence of an atom's structure has been theorized.

Who provided evidence for the exsitist of an atomic nucleus?
This is the well known gold foil experiment: alpha particles are scattered by the atomic nucleus.
