RARE GASES Meaning and
Definition
-
Rare gases, often referred to as noble gases, are a group of chemical elements that are characterized by their low reactivity and existence as monatomic gases under normal conditions of temperature and pressure. This group includes helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). These gases are classified as rare due to their relatively low abundance in the Earth's atmosphere.
Rare gases are distinguished by their filled outer electron shells, making them exceedingly stable and unreactive. This property is a result of their unique electron configurations, which prevent them from readily forming compounds with other elements. As a result, rare gases are commonly used in various applications where their inert nature is required, such as in lighting, lasers, and cryogenics. They are also used in gas-filled tubes and as insulation in high-voltage equipment.
The term "rare gases" is a misnomer, as these elements are present in the Earth's atmosphere, albeit in small quantities. The name derives from their initial discovery when it was believed these gases were extremely rare. However, they are now known to exist in trace amounts, with helium being the second most abundant element in the universe after hydrogen.
In conclusion, rare gases are a group of chemical elements that are chemically inert, monatomic, and possess filled outer electron shells. They are commonly used in industries where their low reactivity is advantageous, and are present in small concentrations in the Earth's atmosphere.

Etymology of RARE GASES
The term "rare gases" or "noble gases" has its etymology rooted in the properties and historical understanding of these elements.
The word "noble" was initially used to describe these gases due to their inertness and reluctance to react with other elements. This property made them appear aloof or dignified, similar to the behavior associated with noble individuals.
The term "rare gases" is based on the relative abundance of these elements in the atmosphere. While some noble gases, like argon, are more abundant than others, they are still comparatively less common than gases like nitrogen and oxygen, which make up most of the air we breathe. Therefore, these gases were referred to as "rare gases" to emphasize their lower concentration in the atmosphere.
