What was sir ernest Rutherford and Niels Bohr's most famous discovery?
Rutherford discovered that the atom has a nucleus, bohr's discovery is found on the Wikipedia Link further down this page.Few question and answers on Bohr's atomic modelThe basic assumption in Bohr's model of an atom is thatThe energy of electron is quantisedIn Bohr's model of the hydrogen atomthe radius of the nth orbit is propotional to n² the angular momentum of the electron in an orbit is an integral multiple of h/2λ the magnitude of potential energy of the electron in any orbit is greater than its K.E.
Contribution of chemistry in technology?
energy, foods and whatever!!!
What is the contribution of arturo alcaraz?
Father of Geothermal Energy of the Philippines is Arturo Alcaraz. His contribution creates a great impact in our life because he is the one that powered an electric bulb through geothermal energy.
When was the Atomic Energy Act passed?
1954
How much of atomic energy can destroy your planet?
If you are asking "how much use of atomic energy can destroy your planet?" Nobody knows yet, but we are finding out now.
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 are the uses of the discoveries of Ernest Rutherford?
Ernest Rutherford's discoveries in nuclear physics led to the development of the atomic model and our understanding of the structure of the atom. His work also laid the foundation for nuclear energy and weapons, as well as advancements in medical imaging techniques like PET scans.
What has the author Robert Rutherford Nimmo written?
Robert Rutherford Nimmo has written: 'Atomic energy'
How did niels bohr differ from ernest Rutherford?
Niels Bohr expanded on Ernest Rutherford's model of the atom by introducing the idea of quantized energy levels for electrons in orbits around the nucleus. He also proposed the concept of electron shell structure. Rutherford, on the other hand, is known for the discovery of the atomic nucleus and his model of the atom as a dense positively charged center with electrons orbiting around it.
What was Ernest Rutherford contribution to the atom?
Ernest did an experiment where he shot alpha particles into a gold foil that proved the concept of a nuclear atom,that is an atom with a nucleus made of protons and neutrons and have electrons moving around the nucleus in some way.His experiment did not show the position of electrons or energy levels or even how they moved.
Who invented the atomic model?
The atomic model was developed by various scientists over time, with contributions from Niels Bohr, Ernest Rutherford, and John Dalton. However, the modern atomic model that we use today, with electrons existing in energy levels around a nucleus, was largely proposed by Niels Bohr in 1913.
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.
Ernest Rutherford's contribution to the atomic structure due to the gold foil experiment?
Ernest did an experiment where he shot alpha particles into a gold foil that proved the concept of a nuclear atom, that is an atom with a nucleus made of protons and neutrons and have electrons moving around the nucleus in some way. His experiment did not show the position of electrons or energy levels or even how they moved.
How did ernest rutherfords discovery help people?
Ernest Rutherford's discovery of the atomic nucleus in 1911 revolutionized our understanding of the structure of atoms, leading to the development of nuclear physics. This discovery paved the way for advancements in nuclear energy, medicine (e.g., radiation therapy), and technology (e.g., nuclear reactors). It continues to contribute to various fields, from energy production to scientific research.
Where is Ernest Rutherford's quote if it were possible to control the rate of disintegration of the radio elements an enormous amount of energy could be obtained from a small amount of matter?
The energy produced by the breaking down of the atom is a very poor kind of thing. Anyone who expects a source of power from the transformation of these atoms is talking moonshine. - Ernest Rutherford
What is the atomic theory of neils bohr?
An atomic theory that patches up the holes in Ernest Rutherford's own. Bohr's theory states that electrons give off energy in bunches, not continously, so as long as the electrons remain in a stable orbit they will have the same amount of energy.
Why did Rutherford's need to be replace?
Ernest Rutherford's atomic model, while groundbreaking, was eventually replaced due to its inability to explain certain phenomena, such as atomic stability and spectral lines of elements. His model depicted the atom as a miniature solar system, but it couldn't account for the behavior of electrons in quantized energy levels. The introduction of quantum mechanics and Niels Bohr’s model, which incorporated quantization and orbital stability, provided a more accurate framework for understanding atomic structure. This shift marked a significant advancement in the field of atomic physics.
