Definition
Argon (Ar) is an element belonging to the noble gas group on the periodic table. It is chemically inert and does not readily participate in chemical reactions under normal conditions.
These are elements located in Group 18 of the periodic table characterized by their stable electron configurations and lack of reactivity due to having full outer electron shells.
Chemical Inertness: This refers to the tendency of certain elements or compounds to be unreactive or non-responsive towards other substances. Like argon, chemically inert substances do not readily undergo chemical reactions.
These are mathematical relationships that describe the behavior of gases, including concepts like pressure, volume, and temperature. Argon's properties can be explained using gas laws.
