What are the least reactive elements?
Understand the Problem
The question is inquiring about the elements in the periodic table that exhibit the least reactivity. This generally pertains to the noble gases, which are known for their lack of chemical reactivity due to having a full valence shell.
Answer
noble gases
The final answer is noble gases, which include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).
Answer for screen readers
The final answer is noble gases, which include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).
More Information
Noble gases are considered the least reactive because they have a full outer valence shell of electrons, leading to very low chemical reactivity.
