Before Rutherford, scientists assumed that the atom was a single particle. Rutherford presented his revolutionary, physical atomic model that suggested an atom consists of a central charge (the term 'nucleus' was coined after Rutherford's model was presented) that is surrounded, presumably, by a cloud of orbiting electrons. He showed that most of an atom's mass was located in the atom's nucleus.
Rutherford's model was later improved upon by Niels Bohr, father of the Bohr-model. Rutherford made no connection to an element's atomic number and the number of protons within an atom's nucleus; however, his atomic model paved the way for the discovery of this correlation only a couple years after his model was designed.
Ernest Rutherford's famous gold foil experiment led to the discovery of the atomic nucleus and the concept of a dense, positively charged nucleus at the center of the atom surrounded by negatively charged electrons. This led to a significant change in the atomic model, shifting from the previously accepted idea of the "plum pudding" model to the nuclear model of the atom.

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.
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.
Whose model was called planetary model of the atom?
The planetary model of the atom was proposed by Ernest Rutherford. It suggested that electrons orbit the nucleus of an atom in a manner similar to planets orbiting the sun.
Which scientist described a positively charged core (nucleus) in the middle of a lot of empty space?
Probably you refer to Ernest Rutherford.
What early theory of atomic structure described electrons as moving around a central nucleus similar to the solar system?
The early theory of atomic structure that described electrons as moving around a central nucleus similar to the solar system is known as the Rutherford atomic model. Proposed by Ernest Rutherford in 1911, this model suggested that electrons orbit the nucleus in defined paths.
Who discovered the nuclear model?
Ernest Rutherford created the nuclear model of an 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.

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?
The planetary model of the atom was proposed by Ernest Rutherford. It suggested that electrons orbit the nucleus of an atom in a manner similar to planets orbiting the sun.
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.
Which scientist described a positively charged core (nucleus) in the middle of a lot of empty space?
Probably you refer to Ernest Rutherford.
When did Ernest Rutherford propose the plum pudding model of the atom?
The ''plum pudding atomic model" is from J. J. Thomson, year 1904.
What early theory of atomic structure described electrons as moving around a central nucleus similar to the solar system?
The early theory of atomic structure that described electrons as moving around a central nucleus similar to the solar system is known as the Rutherford atomic model. Proposed by Ernest Rutherford in 1911, this model suggested that electrons orbit the nucleus in defined paths.
