Guida verificata passo dopo passo1
Understand that the periodic table is organized into groups (vertical columns) and periods (horizontal rows), where elements in the same group share similar chemical properties.
Recall that noble gases are known for their lack of reactivity due to having a full valence electron shell, making them very stable.
Identify the group number associated with noble gases by remembering that they are located in the far right column of the periodic table.
Recognize that this far right column is labeled as Group 18 in the modern periodic table.
Conclude that the group containing the noble gases is Group 18.
