See nuclear shell model-nay, rather Magic number ( physics )-for a diagram of how the largest " known " nuclear shell marks the end of the stable sequence at bismuth.

The shell model was able to qualitatively explain many of the mysterious properties of atoms which became codified in the late 19th century in the periodic table of the elements.
43.
The style has also seen the introduction of a new type of seating : a curved, rounded, individual seat called the " coque ", or shell model, after its distinctive shape.
44.
The four components of the SHELL model or aviation system do not act in isolation but instead interact with the central human component to provide areas for human factors analysis and consideration.
45.
The spherical shell model fairly accurately predicts the energies of protons emitted by unstable isotopes ( forms ) of nuclei containing between 69 protons ( thulium ) and 81 protons ( thallium ).
46.
While he said he has yet to sell one of his pre-fabricated shelters since the attacks, there's been " considerable interest " in a steel shell model that costs about $ 5, 000 installed.
47.
These quantum shells correspond to a set of energy levels within the shell model of the nucleus; filled shells, such as the filled shell of 50 protons for tin, confers unusual stability on the nuclide.
48.
The hypothesis is based upon the nuclear shell model, which implies that the atomic nucleus is built up in " shells " in a manner similar to the structure of the much larger electron shells in atoms.
49.
The SHELL model indicates relationships between people and other system components and therefore provides a framework for optimising the relationship between people and their activities within the aviation system that is of primary concern to human factors.
50.
As with electrons in the electron shell model, protons in the outermost shell are relatively loosely bound to the nucleus if there are only few protons in that shell, because they are farthest from the center of the nucleus.
