According to their location on the Periodic Table, what type of substances are argon (Ar) and neon (Ne)?

Argon and neon are classified as noble gases because they belong to Group 18 of the Periodic Table. This group is characterized by elements that have filled outer electron shells, which leads to their stability and low reactivity. Noble gases are known for their inability to easily form compounds with other elements due to this stability.

The properties of noble gases such as being colorless, odorless, and tasteless under standard conditions further support this classification. In contrast, metals are typically found on the left side and in the center of the Periodic Table, exhibiting properties such as conductivity and malleability. Nonmetals encompass a broader range of elements, including gases, liquids, and solids, but they do not share the distinct characteristics of noble gases. Alkali metals, located in Group 1, are highly reactive and not applicable to argon and neon's characteristics.
