closed shell

The enemy had apparently retired into a tightly closed shell of energy.

There are however problems with the shell model when an attempt is made to account for nuclear properties well away from closed shells.

But the theorists have predicted that there is another closed shell out beyond all elements discovered so far, including the latest one.

Extensive development of these theories were carried by him for molecules, with closed shell configurations.

Cook the cleaned mussels (only those with closed shells) by immersing them into the liquid over high heat for 5 minutes.

Also, buy mussels with tightly closed shells or those that snap shut when tapped - otherwise they're not alive and fresh.

Oysters and mussels should have closed shells.

The quantum theory of the atom explains the eight electrons as a closed shell with an sp electron configuration.

A regular icosahedron is the optimum way of forming a closed shell from identical sub-units.

This is typical of the HF model, which usually describes closed shell systems around their equilibrium geometry quite well.

This area is connected via the last closed shell parameter L with the ionospheric dynamo region.

Structure 2a is a (singlet) diradical and 2b is the closed shell quinoid.

Flourine, which is missing only one electron to form a closed shell is, as expected, extremely active chemically.

For helium there is no 1p level according to the quantum theory, so that 1s is a closed shell with no p electrons.

C fullerene has 60 pi electrons but a closed shell configuration requires 72 electrons.

An example is the stability of the closed shell of 50 protons, which allows tin to have 10 stable isotopes, more than any other element.

The -closo- term is designated to the molecule as a result of its closed shell electron count for boron chemistry.

Ukiah eyed the closed shell.

This is not surprising as in contrast to F an ion S is not a closed shell species.

The Langevin theory of diamagnetism applies to materials containing atoms with closed shells (see dielectrics).

When buying hard-shell clams, remember that live ones have tightly closed shells; reject any whose shells are open or cracked.

We had no knife to open the tightly closed shells, but after he placed them next to the fire, they steamed open, exposing the inner meat.

In contrast a "closed shell" interaction as in an ionic bond has a small electron density and a positive Laplacian.

Such an atom has the following electron configuration: sp; this requires only one additional valence electron to form a closed shell.

This applies in particular for isomers in odd proton-even neutron nuclei, near closed shells.
