Which statement is not true of the atomic model of Bohr?
An electron has the same amount of energy in all orbitals this is not true because depending on how much enegry it has will depend on how many orbitals it has.
An electron has the same amount of energy in all orbitals.
Why do you think bohr was concerned with the future implications of his work on atomic bombs?
A nuclear arms race combined with fear and suspicion could lead to a disastrous nuclear war.
What technology did Bohr use to discover the electron?
The only technology Bohr needed to develop his model for the atom was a spectrometer, which, in the mid-1800s, revealed the emission lines of hydrogen. In 1885, Johann Balmer developed a mathematical formula (the Balmer Series) that fully described these lines, but nobody could explain why it worked.
Neils Bohr combined the quantum ideas of Max Planck and Albert Einstein with the atomic model proposed by Ernest Rutherford, and developed an atomic model from which the Balmer Series could be derived.
Bohr's model provided a theoretical base to the Rydberg formula, but incorrectly involves the idea that electrons orbit the nucleus in circular paths. Schrodinger's equations, which are a model in themselves, fix this and "correctly" involves the idea that electrons are not actual particles with defined points when in an atom, but actually have regions of where they are most likely to be (for example, a 1s electron is 99% probably at the nucleus, whereas a 2p electron will be somewhere in one of two "bubbles" nearby) - the electrons in your body have an extremely small, but still possible, chance of all being in Jupiter right now - and allows us to calculate the properties and locations of these electrons.
What experiments did Neil's Bohr do that inspired his atom model?
See http://www.answers.com/topic/niels-bohr for information that should help.
The Bohr model suggests that electrons orbit the nucleus in circles and that these circles are all in a single plane.
How is the Bohr model better than the Rutherford model?
Bohr formulated new explanation and theories to remove Rutherford defect in Rutherford atomic model thats why Bohr atomic model is better than Rutherford atomic model.
What is the quantum number of the ground state of an atom in the Bohr model?
One possible answer is:
4, 1, -1, +1/2
Another possible solution is:
4, 1, 1, -1/2
What does the bohr-Rutherford diagram of cobalt look like?
it has 28protons and 31 neutrons with 28 electrons and has 5 shells or orbitals. 2 in the first, 8 in the 2nd 3rd and 4th, and 2 in the fifth
What was Happening in history When Niels Bohr became famous?
Niels Bohr became famous in the early 20th century for his contributions to atomic theory, specifically the development of the Bohr model of the atom. This was a time of intense scientific discovery, with groundbreaking work being done in physics, chemistry, and other fields. In particular, Bohr's work was influenced by the emerging field of quantum mechanics and the ongoing debate over the nature of the atom.
Why were original atomic models not as accurate as the models you use today?
Thomson proposed that negative electrons were located throughout a positively-charged atomic mass like plums in a pudding. Rutherford's experiments revealed that most of the mass of an atom was concentrated in a tiny region in its center, the nucleus, surrounded by nearly-massless electrons in their orbitals.
How did Niels Bohr's model of an atom differ from that of his predecessor Ernest Rutherford?
The orbital revolutionof the electron is not expected to be stable.Any particle in a circular orbit would undergo accleration.
During accleration,charged particles would radiate energy.Thus,revolving electrons would lose energy and finally fall into nucleus.If they were so,the atom would be highly unstable and hence matter would not exist in the form that we know.We know that atoms are quite stable.
Niels Bohr won the Nobel Prize for his groundbreaking work in atomic structure and the development of quantum theory. Bohr's work helped to revolutionize physics, as his models of the atom and quantum mechanics explained the behavior of electrons, allowing for a deeper understanding of the physical world. Specifically, Bohr was awarded the Nobel Prize in Physics in 1922 for his:
Bohr's work provided the foundation for much of the research that followed and demonstrated the importance of collaboration in the physical sciences. His Nobel Prize was a recognition of the significance of his contributions to the field of physics.
How is bohr's atomic model different from rutherfords model?
Bohr's atomic model was based upon a famous experiment by Rutherford, who determined that an atom has a small, dense, positively charged nucleus surrounded by negatively charged electrons. Bohr took this information and came up with a "planetary" model where electrons orbit the nucleus in set paths, much like the planets orbit the sun. We now know this is inaccurate, but Bohr's model is still used in teaching because it's a handy way to keep track of how many electrons are in which energy level.
What happens when energy is givien to electrons in bohrs model?
From your question, In Bohr's model of the atom is energy give off or absorbed when electrons give offlight. From the word "off" i think the answer is too obvious, it gives off energy. And that is photon. The particle given off because of excess of electrons. Just get my point.
The bohr model is used to illustrate the arrangement of?
The Bohr model is used to illustrate the arrangement of electrons in an atom, showing them in discrete energy levels around the nucleus based on their quantized energy values.
What contribution of niels bohr to chemistry?
* The Bohr Model of the atom, the theory that electrons travel in discrete orbits around the atom's nucleus. * The shell model of the atom, where the chemical properties of an element are determined by the electrons in the outermost orbit. * The correspondence principle, the basic tool of Old Quantum Theory. * The "Tear Drop Model" of the Atomic Nucleus. * Identified the isotope of uranium that was responsible for slow-neutron fission - 235U. * Lots of work on the Copenhagen Interpretation of quantum mechanics. * The principle of complimentary: that items could be separately analyzed as having several contradictory properties.
Did niels bohr's atom model have a cloud of positive charge?
yes, they are depicted by a red subatomic particle.
Niels Bohr was interested in the field of physics, with a focus on atomic structure and quantum theory. He is known for his work on the development of the Bohr model of the atom, which introduced the concept of quantized energy levels. Bohr also made significant contributions to the understanding of nuclear reactions and nuclear fission.
Why is bohr's theory incorrect?
The Bohr's atom model is still used because of its simplicity, and its correct results for selected systems. The Bohr model is still taught to introduce students to quantum mechanics or energy level diagrams.
What is Niels Bohr country of origin?
Denmark. He was born in Copenhagen and fled from the Nazis during World War II.
What evidence did Bohr analyze to further modify Rutherford's model of the atom?
love compassion
No, but funny.
The correct answers is because He proposed that electrons move around the nucleus in certain paths, or energy levels.
What is the bohr model of the neon element?
The Bohr model describes atoms as having a nucleus surrounded by electrons in fixed energy levels. For neon, which has 10 electrons, the Bohr model would show two electrons in the first energy level, and eight electrons in the second energy level. The electrons in the outermost energy level determine neon's chemical properties.
