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 else can I help you with?
What was the first atomic model to contain empty space within it?
The atomic model that contained empty spaces within it was given by Mendeleev. The gaps were left for the elements that were not discovered at that time.
Which scientist was the first to describe an atomic model in which most of the atom is empty space?
Ernest Rutherford was the first scientist to describe an atomic model in which most of the atom is empty space. His model proposed that atoms have a dense positive nucleus surrounded by orbiting electrons in empty space.
What did Ernest Rutherford add to are knowledge of atoms?
Ernest Rutherford's gold foil experiment led to the discovery of the atomic nucleus and the proposal of the nuclear model of the atom. He demonstrated that atoms are mostly empty space with a dense, positively charged nucleus at the center. This helped pave the way for further understanding of atomic structure and the development of the modern atomic theory.
What was sir Ernest Rutherford's major contribution to science?
He completely changed the atomic model of his time to something that is quite similar to the current model of the atom. His "alpha scattering experiment" provided the evidence that the atom was mainly empty space, and that most of its mass and all of its positive charge was located in a small, dense core(now called the nucleus).
Who developed a new atomic model about five years after Thomson?
About five years after J.J. Thomson proposed his atomic model in 1897, Ernest Rutherford developed a new atomic model in 1911. Rutherford's model was based on his gold foil experiment, which demonstrated that atoms have a small, dense nucleus surrounded by orbiting electrons. His findings shifted the understanding of atomic structure, leading to the Rutherford model, which laid the groundwork for later developments in atomic theory.
Who discovered the nuclear model?
Ernest Rutherford created the nuclear model of an atom!
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.
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.
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 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.
Whose model was called planetary model of the atom?
its was Ernest Rutherford who proposed the planetary atomic model
What was the first atomic model to contain empty space within it?
The atomic model that contained empty spaces within it was given by Mendeleev. The gaps were left for the elements that were not discovered at that time.
What was Ernest Rutherford's biggest contribution to chemistry?
In 1911, Rutherford proposed a new model for the atom. His experiments were the first to show that the atom must consist of a very tiny positively charged nucleus surrounded by negatively charged electrons. (For the record, Rutherford also discovered and named alpha, beta and gamma radiation.)
Which scientist was the first to describe an atomic model in which most of the atom is empty space?
Ernest Rutherford was the first scientist to describe an atomic model in which most of the atom is empty space. His model proposed that atoms have a dense positive nucleus surrounded by orbiting electrons in empty space.

How did Ernest Rutherford change the atomic model based on his experimental results?
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 described a positively charged core (nucleus) in the middle of a lot of empty space?
Probably you refer to Ernest Rutherford.
