Sentences with phrase «electron shell»

It covers GCSE concept of electron shells compared to sub-levels, orbitals, rules for filling, short hand configurations and deciding on the blocks in the periodic table.

Moreover, if these photons are to have a chance of reaching the inner electron shells, they must have energies in the upper end of the extreme ultraviolet (XUV) spectrum.

All lanthanides except lutetium are f - block elements, corresponding to the filling of the 4f electron shell.

In addition, by altering the laser polarization, the researchers demonstrated the ability to influence the dynamics of the restructuring of a molecule's electron shell using a laser field.

Under the effect of powerful and very short laser pulses, the molecule's electron shell configuration changed: a «hole» appeared — a shell vacancy which then began to oscillate moving from one end of the molecule to the other.

Also called inert gases, they have complete outer electron shells and were believed not to react with other elements or compounds.

In such compounds atoms of these elements have some inner electron shells that are incomplete, causing their unpaired electrons to spin like tops and orbit like satellites, thus making the atoms a permanent magnet tending to align with and hence strengthen an applied magnetic field.

An atom is a point in space (unless you consider the shape of the electron shells).

And that is true in Bergson's concept of the pulsations of matter, which then is like the 1926 - 1927 quantum physics, and not like the earlier Niels Bohr model of quantum physics where the pulsations are perfectly distinct, going from one electron shell to the other without passing through the intervening space.

These timekeepers are based on precise knowledge of the frequency of specific transitions between defined energy levels in the electron shells of certain atoms.

When this doesn't quite deliver the desired results, it adds on «shells» that, like the electron shells envisaged to form an atom's outer coat, can each hold a certain number of protons and neutrons.

Just as an atom with a full outer electron shell is a peculiarly unreactive noble gas, an outer shell with the right number of protons and neutrons makes a nucleus magically stable.

Editor's note: This story was updated February 12, 2018, to clarify how oganesson could be chemically reactive and on February 14, 2018, to correct the description of the element's electron shells in the sidebar.

The discrete nature of the particle may be explained by the closing of a 58 - electron shell.

The ultrahigh - resolution images provide information on the distribution of charges in the electron shells of single molecules and even atoms.

«Even greater levels of accuracy could be achieved with the help of a so - called nuclear clock, based on oscillations in the atomic nucleus itself rather than oscillations in the electron shells surrounding the nucleus,» says Thirolf.

Using methods of attophysics, the researchers are trying to track the ultrafast movement of electrons in molecules, or more precisely the restructuring of their electron shells.

By irradiating oriented molecules with powerful laser pulses, the researchers were able to obtain high - harmonic spectra reflecting the state of a molecule's electron shell.

To better understand the complex influence of the electron shell on measurements of nuclear magnetic moments, scientists at TU Darmstadt now want to conduct measurements of nuclear magnetic moments on atomic nuclei with just a single bound electron or no electron shell at all.

Free radicals are molecules with incomplete electron shells which make them more chemically reactive than those with complete electron shells.

When Saul dies, Simon is in physics class, drawing concentric circles meant to represent the rings of an electron shell but which to Simon mean nothing at all.

With his daydreaming and his dyslexia, he has never been a good student, and the purpose of the electron shell — the orbit of electrons around an atom's nucleus — escapes him.
