What are Noble Gases? Define Noble Gases
Noble Gases are used as a term in
when classifying the chemical elements. Each element can usually be classified
as a metal or a non-metal based on their general
Physical and Chemical Properties.
The 6 elements classified as "Noble Gases" are located in Group 18 of the
Periodic Table. Because the outermost electron
shell of atoms of these gases is full, they do not react chemically with other
substances except under certain special conditions. Noble Gases are also known
as the inert gases. The noble gases are not reactive. This is because they have
little tendency to gain or lose electrons. The elements categorised as Noble
Gases are used to make lighted signs, refrigerants, and lasers.
Origin of the term 'Noble Gas'
The term 'Noble gas' derives from the
Old High German word Edelgas from 'edili' meaning "noble". The name 'noble
gases' is an allusion to the old, similarly termed 'Noble Metals'. The Noble
Metals included Gold,
Platinum. Noble Metals were so called due to their long association with the

electro-negativities. Noble gases are fairly non-reactive and have low boiling
