Which group of elements is the least reactive?
Understand the Problem
The question is asking about the chemical groups of elements and their reactivity. Specifically, it seeks to identify which group of elements is characterized by having the lowest reactivity.
Answer
Group 18 (noble gases)
The least reactive group of elements is Group 18, also known as the noble gases.
Answer for screen readers
The least reactive group of elements is Group 18, also known as the noble gases.
More Information
Noble gases are the least reactive due to their full outer valence shell, making them very stable.
Tips
A common mistake is confusing reactivity with stability; elements with full valence shells are stable, thus less reactive.
