Electron Shell

Description:

The electron shell, also known as the atomic shell or energy level, is the region surrounding an atomic nucleus where electrons are found. It is composed of a set of orbitals that possess similar energy levels. The shells are designated by a series of numbers (n=1, 2, 3...) or letters (K, L, M...) that represent the principal quantum number.

Senses:

1. Atom Structure:

In atomic physics, an electron shell refers to the hierarchical arrangement of electrons around the nucleus of an atom. Electrons occupy different shells depending on their energy levels and their distance from the nucleus.
