Sentences with phrase «which electrons orbited»

Rutherford's atomic model described a new world of worlds in which electrons orbited a nucleus like planets encircling the sun.

The orbit of an electron around a nucleus conceived as a route of occasions would not significantly differ from that orbit conceived as the route of the continuous motion of the electron.2 Hence, Whitehead gave up his work on reformulating the equations of relativity theory, as well as any quest for ways in which his initial work would yield some confirmably different prediction from those of the equations of orthodox relativity theory.

The history of science provides many examples of this combination of analogy and innovation in the creation of models which were useful in generating theories.4 The «Bohr model» of the atom, in which «planetary» electrons revolve in orbits around a central nucleus, resembles the solar system in certain of its dynamical properties; but the key assumption of quantum jumps between orbits had no classical parallel at all.

The satellite, which swoops on an egg - shaped orbit to within 350 kilometers of Earth's surface, detected electrical impulses from electrons coursing upward within charged sheets that shadow the downward flowing auroral electrons.

Ionizing radiation is a type of particle radiation in which an individual particle (for example, a photon, electron, or helium nucleus) carries enough energy to ionize an atom or molecule (that is, to completely remove an electron from its orbit).

The quantum hall materials are one prominent example in which electrons are trapped in non-conducting circular orbits except at the edges of the material.

According to Einstein's theory of relativity, objects travelling this fast will become heavier, which should change the electrons» orbits.

But a second generation is already up and running, and encompasses this new study, in which electrons» own spin - orbit interaction acts on them as if there were a real external magnetic field, even if there is not.

One of the most ubiquitous is the «octet rule,» which states that each atom in a molecule that is produced by a chemical reaction will have eight outer orbiting electrons.

El - Sayed is known throughout physical chemistry for «El - Sayed's Rule,» which handles complexities of electron spin orbits, and which has found a lasting place in photochemistry textbooks.

The material of their choice, the compound Ag2BiO3, is exceptional for two reasons; on the one hand it is composed of the heavy element bismuth, which allows the spin of the electron to interact with its own motion (spin - orbit coupling)-- a feature that has no analogy in classical physics.

Illuminating the quantum dot with laser light excites an electron, which can then jump from one orbit to another and thereby emit a single photon at a time.

This turned them into Rydberg atoms, in which the electrons are in high - energy states and so orbit further away from the positively - charged nucleus.

The trick is to tune the lasers to exactly the energy needed to boost the positronium into a higher energy state, in which the electron and positron orbit farther from one another.

«Ever since the beginning of quantum mechanics people have been looking for a configuration which could explain the stability of atoms and why orbiting electrons do not radiate,» Dr Miroshnichenko said.

A single electron orbiting a proton can occupy only certain, discrete energy levels, which are described by the laws of quantum mechanics.

The perplexing thing about this atom: the radius of the orbit, on which the electron moves around the nucleus, is much larger than the typical distance between two atoms in the condensate.

Rydberg atoms are atoms, in which one single electron is lifted into a highly excited state and orbits the nucleus at a very large distance.

They found that the limit of the variational solution approaches the model of hydrogen developed by physicist Niels Bohr in the early 20th century, which depicts the orbits of the electron as perfectly circular.

The control over the electron wavefunction requires interfaces which lead to the loss of bulk properties of the qubit due to physical processes like the valley - orbit coupling, exchange, and many - body effects in coherent coupling.

Which is why light manifests in the form it does, because in order to be perceived, it must journey, and in ding so, removes one straight line vector of motion, from within the shape of jitter, which is the distribution pattern of electron orbits, and becomes perceived as the wave pattern we see iWhich is why light manifests in the form it does, because in order to be perceived, it must journey, and in ding so, removes one straight line vector of motion, from within the shape of jitter, which is the distribution pattern of electron orbits, and becomes perceived as the wave pattern we see iwhich is the distribution pattern of electron orbits, and becomes perceived as the wave pattern we see it as.

It is easy to observe that H only emits very specific energies of light which are «easily» predicted by the quantum mechanics of the orbiting electrons and the allowed transitions between energy levels of those orbits.

Here the energies are not related to electrons jumping to other orbits (that takes too much energy), but instead it is related to rotations and vibrations of the molecules (which can happen at the energies associated with IR photons).

The models can be viewed in either the traditional Bohr model, which shows an atom with a central nucleus with electrons in orbit around it, or with the quantum mechanical model, which shows off the atom as an electron cloud.
