Which elements on the periodic table are the least reactive? (1 point)

Question

Responses

the group with fluorine at the top
the group with fluorine at the top

the group with hydrogen at the top
the group with hydrogen at the top

the group with helium at the top
the group with helium at the top

the group with carbon at the top

Answer 1

The least reactive elements on the periodic table are found in the group with helium at the top, which corresponds to the noble gases. Noble gases, including helium, neon, argon, krypton, xenon, and radon, are characterized by their full valence electron shells, making them very stable and unreactive under normal conditions. Therefore, the correct response is:

the group with helium at the top.
