Why does the concept of Bohr orbits violate the uncertainty principle?
Wiki User
∙ 12y ago
The Bohr Model of a single-electron atom assumes that the energy levels of electron orbits are fixed due to the quantization of angular momentum of the electron while in orbit.
The problem occurs because angular momentum depends on both the radius of the orbit and the velocity of the electron in that orbit. If one or the other is uncertain, then it is impossible to know the angular momentum.
Heisenberg showed that either one or the other MUST be uncertain. If we are certain about the radius, we MUST have uncertainty about the velocity -- and vice-versa.
Thus, angular momentum of an orbting electron can NOT be quantized, because it can not be known.

Which principle was unknown in the time of Copernicus but later made it possible to explain a mechanism by which the earth orbits the sun?
The gravity of the sun attracts the earth.
Why do electrons go in the next orbit when there is a place in penultimate orbit?
due to aufbau principle the energy of the ultimate sub-orbits are less than the energy of the penultimate orbitals
What Orbits and is Orbited?
Earth. It orbits the sun and the moon orbits it
When does the moon move?
It always moves it orbits the Earth which orbits the sun.
What is the technical name for planetary orbits?
"Planetary orbits" is the technical term.
What is the position of the electrons in Bohr'smodel?
Defined orbits around nucleus, no uncertainty principle
How are electrons distributed in different orbits?
according to Aufbau principle
Who introduced the concept of elliptical orbits to explain the splitting of the spectral lines?
Arnold Sommerfeld
Which principle was unknown in the time of Copernicus but later made it possible to explain a mechanism by which the earth orbits the sun?
The gravity of the sun attracts the earth.
How can you be sure today that the Earth orbits around the sun?
There is no evidence whatsoever that it does not. There are huge amounts of data supporting the concept that earth orbits the sun.
How does Gravity affect your planets?
Our planets are kept in their orbits around our star by the force of gravity.With all due respect, I should be surprised if the principle were not the samewhere you come from.
How do planets float in space without gravity?
Planets do have gravity and are affected by it and they don't exactly float. They orbit the sun, which requires moving very fast. When you think about it, an orbit is something of a strange concept. When you throw and object, it follows a path that curves downward. The faster you throw it, the broader the curve. A similar principle applies to orbits. An planet in orbit is essentially in perpetual freefall, but its "sideways" motion creates a curve large enough that it continously misses the sun. All orbits work in this way
Why do electrons go in the next orbit when there is a place in penultimate orbit?
due to aufbau principle the energy of the ultimate sub-orbits are less than the energy of the penultimate orbitals
How many orbits in the third row have?
The third row, or period, has 6 electrons.The concept of "orbits" for the third (or any) row does not make sense. Please restate the question, giving more details, if I did not answer it to your satisfaction.
What is a quantum shell?
The quantum shell or the principle shell (represented by an integer known as the principle quantum number, n) are orbits found in an atom. It is arranged as n=1, n=2, and so forth, n=1 being closest to the nucleus. As the numbers increase, so do the energy. Each quantum shell is an orbit, and in the orbits exist sub-orbitals. Please see sub-orbitals for more details.
What Orbits and is Orbited?
Earth. It orbits the sun and the moon orbits it
What is the simple definition and concept and application of magnetic field?
Magnetic fields are produced by electric currents, which can be macroscopic currents in wires, or microscopic currents associated with electrons in atomic orbits
