How to read this

Every construct on the map is compared with every other by the meaning of its definitions, and the closest one is surfaced here. The nearest construct to shell is mantle.

Hold this as a prompt, not a verdict. Two constructs sitting close in meaning is a reason to read them side by side and decide for yourself whether they are one idea under two names. It is not proof that they are. Compare the meanings in the Collider.

Chemistry & physics

a group of electrons occupying one allowed, quantized energy level around the atomic nucleus.

In the Bohr model of the atom, a shell is a group of electrons occupying one allowed, quantized energy level around the nucleus. Bohr introduced the idea in 1913 to explain why atoms emit light at fixed wavelengths: an electron jumps between shells and the energy gap sets the colour. The referent is a quantized energy level, not a material object, and it is inferred from spectral lines rather than seen. It shares the word shell with a protective covering and a command-line program, but here the shell is an abstraction inside a model of the atom, measured in electron-volts.[1]

A group of orbitals at one principal energy level

Measured by
Spectral lines and ionization energies, read as transitions between energy levels

Finance & law

a registered business that exists only on paper, with no significant operations, employees or trade.

A shell company is a business that exists only on paper: it is registered, with owners, an address, and perhaps a bank account, but has no significant operations, employees, or trade. Findley, Nielson, and Sharman showed in Global Shell Games in 2014 how easily such entities are formed and used to hold assets or hide who controls them. The referent is a legal entity, and what defines it is emptiness: the corporate form is real but the activity inside is not. It inverts the other meanings, where the shell surrounds something real; here the shell is the whole of the thing.[2]

Unit
A registered legal entity with no operations
Recovery means
Not applicable
Measured by
Identified from company registries: owners and an address, but no employees, assets, or trade
