What Is an Electron Shell?


Electron shell refers to the outside part of an atom around the atomic nucleus. They are 'clouds' of electric charge and they usually determine the chemical properties of the atom. Normally each shell consists of one or more sub shells, and each sub shell consists of one or more atomic orbital's.

Electron shells are orbits that are followed by electrons around an atom's nucleus. They are numbered from the closest to the nucleus and they can only contain up to certain amounts of electrons. The chemical properties of the atom are determined by the outermost shell.
An electron shell is the layer that is formed and surrounds the nucleus of an electron. It is also thought of an orbit followed by electrons around an atom nucleus.  Each shell can contain only a fixed number of electrons so each shell is associated with a particular range of electron energy, and thus each shell must fill completely before electrons can be added to an outer shell.
An electron shell is the ring around the nucleus of an atom which contains electrons that share the same principal quantum numbers. The inner shells of an atom are always full but the outer ones are filled with varying numbers of remnant electrons. The shells are occupied in the 2 8 8 18 configuration from the innermost to the outermost.
An electron shell is also known as an electron orbital. These are the orbitals the surround an atom's nucleus. Electrons are housed in these shells.
