Interpretation: Meaning of the term noble when referring to noble metals and noble gases needs to be explained.
Concept introduction: A table in chemistry, where all elements are arranged by increasing
Answer to Problem 4RQ
Those elements that are not very reactive, called noble.
Explanation of Solution
The periodic table is a very useful way to arrange elements. Noble refers to the fact that the metals and gases are relatively unreactive. Also, noble implies a class set apart from other elements. Because of inertness and chemical resistance, noble metals are corrosion and oxidation resistant. Noble gases are inert, stable and unreactive. So, when referring to noble metals and noble gases, meaning of the term noble is “not very reactive”.
Noble metals and noble gases are stable and not so reactive.
