Alikuoriin

Alikuoriin is a Finnish term used in atomic physics and chemistry to refer to subshells within an atom’s electron structure. The base word alikuori means “subshell,” and the form with the suffix -in is used in contexts indicating movement toward or into these subshells in Finnish texts. In practice, alikuoriin appears in explanations of how electrons are distributed among the available subshells (such as 1s, 2s, 2p, 3s, 3p, 3d, and so on) when constructing an electron configuration.

In atomic theory, subshells are subdivisions of electron shells defined by quantum numbers. Each subshell is labeled by a letter (s, p, d, f) and can hold a specific maximum number of electrons. The arrangement of electrons into alikuoriin follows principles such as the Aufbau principle, Pauli exclusion principle, and Hund’s rule, and it influences the chemical properties of elements. Finnish-language texts often describe electron occupancy by naming the subshells into which electrons are placed, for example “säiliöt alikuoriin 1s^2 2s^2 2p^6 …” to illustrate the stepwise filling process.

Usage and scope: alikuoriin is a specialized term mainly found in Finnish educational and scientific materials. It is part of the broader concept of electron configuration and atomic orbitals, and is typically encountered in high school and university-level chemistry or physics discussions in Finnish.
