Noble Gases Location in Periodic Table
The periodic table organizes elements based on their atomic structure and recurring chemical properties. Specific blocks or columns, known as groups, contain elements with similar characteristics.
Identifying the Noble Gases Group
The noble gases are a group of chemical elements with distinct properties. They are known for their very low reactivity under standard conditions.
- These elements are located in the rightmost column of the periodic table.
- Historically, they were called "inert gases" due to their lack of reactivity.
- The specific group number containing the noble gases is Group 18.
Common examples of noble gases include Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn).
Therefore, Group 18 of the periodic table consists of the elements known as the noble gases.
