Question

Responses

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

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

the group with fluorine at the top
the group with fluorine 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 is the noble gases. Noble gases, located in Group 18 (or Group 0), are characterized by their complete valence electron shells, making them very stable and unreactive under normal conditions. Therefore, the correct response is:

the group with helium at the top.
