What year did Niels Bohr find that most of an atom mass is in the nucleus?
This discovery is from Ernest Rutherford (approx. 1913).

The ''plum pudding atomic model" is from J. J. Thomson, year 1904.

What year were found protons?

What year did ernest Rutherford make a contribution to the atomic model?
He didn't exactly "discover" the nucleus. In 1911 he theorized about the atom having its positive charges in a very small nucleus. In 1921 he postulated about the existence of the neutron in the nucleus. The first experiment to split the atom in a controlled manner was performed by him and two students in 1932.

What year did Ernest Rutherford add to our knowledge?
Ernest Rutherford contributed significantly to our understanding of atomic structure in the early 20th century. His famous gold foil experiment in 1909 led to the discovery of the atomic nucleus.
What year was Ernest Rutherford born on?

Who discovered beta rays?
Ernst Rutherford discovered beta decay. Henri Becquerel discovered that there were emissions somewhat like X-rays originating from uranium. Ernst Rutherford discovered that two different kinds of emissions were coming from the uranium, and he named these alpha and beta. He published a paper on this in 1897.
Who identified the nucleus of an atom?
The nucleus of an atom is far too small to be "seen" in any conventional sense. The structure of the atom, that is, the one with most of the mass of the atom concentrated in the center, or nucleus, was developed by physicist Ernest Rutherford. In a sense, he is the one who first "saw" the nucleus of the atom. A link to the Wikipedia article on the atom, an article which includes the history of discoveries that lead to modern concepts of it, is provided. A link is also provided to the Rutherford model of the atom, also at Wikipedia. Hey, the nice folks at Wikipedia post knowledge for free. Why not surf on over and help yourself? It's a buffet, with all you can eat.
