Sentences with phrase «by electrons orbiting»

It's the result of a particular magnetic property of materials — the magnetic moment, a tiny magnetic field produced by electrons orbiting the nucleus of an atom.

Not exact matches

Conceivably, the earlier phases fade before the later, in the same sense that antecedent moments in the orbit of an electron no longer exist by the time the orbit is complete.
Scientists don't fully understand what's driving Jupiter's strongest auroras, but data gathered by the orbiting Juno spacecraft hint that the electrons generating Jupiter's polar glows may be accelerated by turbulent waves in the planet's magnetic field — a process somewhat akin to surfers being driven shoreward ahead of breaking ocean waves, the researchers report today in Nature.
All light comes from the same physical process: An electron circling the nucleus of an atom in its customary orbit is energized — often by heat — and moves into a higher orbit.
An antimatter nucleus is negative instead of positive, and it is orbited by positrons, electrons that are positive instead of negative.
In incandescent light, the trigger to push electrons into a higher orbit is heat provided by electricity passing through a carbon filament in a vacuum; in bioluminescence, the electrons are pushed up by two chemicals working together.
In the sea of graphene (over an iridium crystal), electrons» spin - orbit interaction is much lower than that created by intercalating a Pb island.
The atom is a helium nucleus orbited by an electron and an antiproton rather than two electrons.
Electrons occupy different orbits around their atom and, by analogy, spin like Earth.
When energy is added to the material, either by a laser «pump» or as an electrical current, it kicks some of the electrons orbiting the molecules into higher energy states.
The most accurate atomic clock we have now is regulated by the electrons of a single aluminium ion as they move between two different orbits with sharply defined energy levels.
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.
All the elements in the periodic table consist of atoms with a nucleus of positively charged protons, orbited by the same number of negatively charged electrons.
Hydrogen nuclei each consist of a single proton, orbited by an electron.
A single electron orbiting a proton can occupy only certain, discrete energy levels, which are described by the laws of quantum mechanics.
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.
X-rays are produced in X-ray tubes by the deceleration of energetic electrons (bremsstrahlung) as they hit a metal target or by accelerating electrons moving at relativistic velocities in circular orbits (synchrotron radiation; see above Continuous spectra of electromagnetic radiation).
These are necessarily the same as the energy states of the molecules are determined by the allowable electron orbits.
As the electrons of the molecules of air absorb visible light they are physically moved in their orbit before coming back to ground state when they spit out the same energy they absorbed, the energy is conserved by the electrons using it in moving in their orbit and is conserved in the loss of speed of the visible light.
In the atmosphere the absorption of visible light's energy by the electrons of the gas air does not create heat, the energy is used in motion through space (think petrol in the car used for motion through space), as the electron is moved in its orbit and when returning to ground state when it spits out the same energy as entered; the right kind of energy and an electron can be moved out of its orbit completely.
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.
The Bohr model of the hydrogen atom: a dense nucleus containing the hydrogen atom's single proton (and possibly one or more neutrons), surrounded by an electron that can be on one of several different orbits.
Radiation from a molecule at -80 C therefore can not provide enough energy in the form of photons, to warm molecules (by boosting electrons into higher, more energetic orbits) at -4 C or above (seawater temperatures).
