Ernest Rutherford's famous gold foil experiment led to the discovery of the atomic nucleus. This discovery changed the atomic model by replacing the plum pudding model with the planetary model, where electrons orbit a central nucleus. Rutherford proposed that the nucleus contained positively charged protons while the electrons orbited around it.

Which scientist developed atomic model?
John Dalton developed the first modern atomic theory in the early 19th century, proposing that elements are made up of tiny, indivisible particles called atoms. Later, Ernest Rutherford's gold foil experiment in 1911 led to the discovery of the nucleus and the planetary model of the atom.
What scientist said most of the mass of the atom is in tiny dense positively charged nucleus?
Ernest Rutherford is the scientist who proposed that most of the mass of an atom is concentrated in a small, dense, positively charged nucleus, based on his gold foil experiment which led to the discovery of the atomic nucleus.
Which scientist described a positively charged core (nucleus) in the middle of a lot of empty space?
Probably you refer to Ernest Rutherford.
Who came up with the idea of a nucleus of an atom?
Ernest Rutherford is credited with proposing the concept of a dense, positively charged nucleus at the center of an atom in his gold foil experiment in 1909. This experiment provided evidence for the existence of the atomic nucleus.
What is the contributions of Ernest Rutherford?
Ernest Rutherford made significant contributions to the field of nuclear physics. He is known for his work on radioactivity and for proposing the nuclear structure of the atom, which led to the development of the planetary model of the atom. Rutherford also conducted the famous gold foil experiment that led to the discovery of the atomic nucleus.

What was Rutherford atomic model called?
The Rutherford-Atomic Theory was published by Ernest Rutherford. It described the atom as having a central positive nucleus surrounded by negative orbiting electrons.
Which scientist developed atomic model?
John Dalton developed the first modern atomic theory in the early 19th century, proposing that elements are made up of tiny, indivisible particles called atoms. Later, Ernest Rutherford's gold foil experiment in 1911 led to the discovery of the nucleus and the planetary model of the atom.
Who Ernest Rutherford?
Ernest Rutherford was an investigator of atomic theory, and it was his model of the atom, the one with the mass concentrated in the center, that replaced the J.J. Thompson model. Links are provided below.
Who is credited with discovery of the atomic nucleus?
Ernest Rutherford is credited with the discovery of the atomic nucleus. In 1911, his gold foil experiment led to the conclusion that most of an atom's mass is concentrated in a small, dense nucleus at its center.
What is the contribution of ernest Rutherford in development of atomic theory?
Ernest Rutherford is known for his famous gold foil experiment, which led to the discovery of the atomic nucleus and the proposal of the nuclear model of the atom. His work helped to refine the understanding of the structure of the atom and laid the foundation for the development of modern atomic theory.
What was Rutherford's contributions to the atomic theory?
Ernest Rutherford contributed to the atomic theory through his gold foil experiment. He discovered that there was a positively charged central core to the atom and he called it the nucleus.
