ELECTRON SHELL Meaning and
Definition
-
An electron shell refers to the arrangement of electrons around the nucleus of an atom. In an atom, electrons occupy distinct energy levels, otherwise known as electron shells or energy shells. Each electron shell can hold a specific number of electrons, determined by its capacity to accommodate electrons based on their energy levels. The shells are designated by numbers, with the first shell closest to the nucleus being the lowest energy level. The second shell is of higher energy than the first, and so on.
The electrons in an atom tend to occupy the innermost available shells before moving to higher energy shells. This principle is known as the Aufbau principle. The innermost shell can hold a maximum of two electrons, while the subsequent shells have higher capacities. The second shell, for instance, can contain up to eight electrons. However, it's important to note that electron shells don't always reach their maximum capacity.
The electron shells contribute significantly to the chemical behavior of an atom. Electrons in the outermost shell, also called the valence shell, are particularly crucial as they determine the atom's reactivity and its ability to form chemical bonds with other atoms. Atoms with full valence shells, known as noble gases, tend to be chemically stable and less likely to form bonds. Conversely, atoms with incomplete valence shells tend to interact readily with other atoms to achieve a more stable configuration by either accepting or donating electrons.

Etymology of ELECTRON SHELL
The word "electron" originates from the Greek word "ēlektron", which means "amber". Amber was one of the first known materials to exhibit the properties of static electricity, and the ancient Greeks named this phenomenon after amber. In the late 19th century, the term "electron" was introduced by the physicist George Johnstone Stoney to describe the fundamental unit of electric charge.
The word "shell" in the context of electron shells comes from the concept of shells or layers that surround a nucleus. This idea was developed by the Danish physicist Niels Bohr in 1913. He suggested that electrons occupy specific discrete energy levels or shells around the nucleus of an atom and move in orbit-like paths within these shells.
Therefore, "electron shell" combines the term "electron" to describe the fundamental charged particle and the term "shell" to represent the energy levels or layers in which electrons are arranged around the nucleus of an atom.
