NOBLE GASES Meaning and
Definition
-
Noble gases are a group of chemical elements that make up a specific column of the periodic table. This group consists of helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). These elements are referred to as noble gases due to their relatively low reactivity and reluctance to form chemical bonds with other elements.
The noble gases are characterized by their full valence electron shells, which makes them chemically stable. As a result, they have little chemical affinity for other elements and do not readily participate in chemical reactions. This property is attributed to their completely filled outermost electron shell, which provides a high energy barrier for the addition or loss of electrons.
Noble gases are colorless, odorless, tasteless, and nonflammable at standard conditions. They are gases at room temperature and do not easily liquefy or solidify. They possess low boiling and melting points, which make them useful in various applications such as lighting, cooling, and cryogenics.
These elements occur naturally in small amounts in the Earth's atmosphere and are present in larger quantities in some minerals and underground deposits. They can be extracted from air through a process called cryogenic distillation or from other sources such as natural gas. Noble gases have applications in various fields including lighting, lasers, gas chromatography, medical imaging, and anesthesia.
In summary, noble gases are a group of chemically inert elements with filled outer electron shells, making them stable and unreactive. They possess unique physical and chemical properties, which contribute to their wide range of applications in different industries.

Etymology of NOBLE GASES
The term "noble gases" was coined in the late 19th century by the British chemist Sir William Ramsay. He discovered a group of previously unknown elements: helium, neon, argon, krypton, and xenon. These elements, unlike many others, were found to be extremely unreactive and did not readily combine with other elements to form compounds. Ramsay compared their behavior to that of the noble class of society, which typically maintained an air of aloofness and did not easily mingle with the lower classes. Hence, he called these elements "noble gases" to reflect their unreactive nature. Later on, the element radon was also included in this group, completing the noble gases as we know them today.
