Group 18 Elements
Group 18, also known as the noble gases, are a group of elements in the periodic table that exhibit characteristic properties due to their configuration. The group is located in the far right side of the table, adjacent to Group 1 ( alkali metals) and Group 17 ( halogens).
Properties:
Noble gases have an extremely high atomic number, resulting in very few valence electrons. This leads to a complete outer electron shell, giving them exceptional stability and unreactivity.
They are highly unreactive due to the shielding effect of the inner core electrons.
The inert nature of noble gases is often attributed to their exceptionally strong bonds with one another.
They exhibit a high boiling point and melting point due to the strong forces holding them together.
Noble gases have relatively low reactivity due to the shielding effect of their valence electrons.
Examples:
Argon (Ar) is a noble gas that is colorless, odorless, and non-flammable.
Neon (Ne) is a noble gas that is colorless, odorless, and non-flammable.
Helium (He) is the lightest noble gas, and is colorless, odorless, and non-flammable.
The study of Group 18 elements provides valuable insights into the properties and behavior of these unique and important substances. Noble gases are widely used in various industries, including manufacturing, medicine, and research
