Ernest Rutherford used the technology of radioactivity and conducted the famous gold foil experiment to discover the structure of the atom. By directing alpha particles at a thin gold foil, he observed how they were deflected, which led to the understanding that atoms have a small, positively charged nucleus at their 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.
Who said that an atom has a small positively charged nucleus surrounded by a large region?
ernest rutherfold
Which scientists proposed the nuclear a tomic model with a centrally located positively charged nucleus based on the result of his gold foil experiment?
Ernest Rutherford published a paper proposing the planetary model in 1911. This followed the experiment performed by Hans Geiger and Ernest Marsden under the direction of Rutherford in 1909, where gold foil was bombarded with alpha particles .
Which scientist developed a model of the atom that looked like a nucleus surrounded by electrons?
The scientist that developed the iconic atom model that depicts a nucleus surrounded by electrons was Ernest Rutherford. Rutherford developed the model in 1911 after displaying some experiments that showed that the J.J.Thomson model was incorrect. Rutherford's experiment showed that an atom is a small but heavy central particle and is surrounded by a cloud of electrons. This was the opposite of what Thomson's model proposed.
How did Ernest Rutherford use the scientific method?
The Ernest Rutherford's atomic method describes the atom as a tiny, dense, and positively charged core. The nucleus has concentrated mass around which the negative constituents, called electrons, circulate at some distance.
Who helped in his laboratory by Hans Geiger and Ernest Marsden?
They were under the supervision of Rutherford
Who helped establish the organization of the atom through experimentation with alpha particles?
Ernest Rutherford
Who discovered that atoms contain mostly with empty space?
Ernest Rutherford.... The Great Scientist.Hope this helped! :D
Who developed the idea of the nuclear atom?
Democritus (460BC - 370BC)
How did ernst Rutherford contribute to scientific knowledge?
Ernest Rutherford helped further develop the atomic theory though his was still not the most correct. He created his Rutherford model for atoms, later corrected further by Bohr.
What was ernest Rutherford's effects on the world?
Ernest Rutherford's experiments on radioactivity led to the discovery of the atomic nucleus, laying the foundation for our understanding of the structure of atoms. His work ultimately paved the way for the development of nuclear physics and the harnessing of nuclear energy. Rutherford's research also had a significant impact on the field of chemistry, as it helped to establish the concept of isotopes.
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.

How have scientists like JJ Thomson Ernest Rutherford and Niels Bohr helped to change and improve your scientific understanding of the atom?
Scientists like JJ Thomson, Ernest Rutherford, and Niels Bohr were pioneers in advancing our understanding of the atom. Thomson discovered the electron and proposed the plum pudding model, Rutherford conducted the gold foil experiment leading to the discovery of the atomic nucleus, and Bohr introduced the idea of quantized electron energy levels and the planetary model of the atom. Together, their contributions laid the foundation for modern atomic theory and our understanding of the structure of atoms.
