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 carbon at the top
the group with carbon at the top

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

Answer 1

The elements on the periodic table that are the least reactive are in the group with helium at the top, which are the noble gases. Noble gases such as helium, neon, argon, krypton, xenon, and radon are known for their lack of reactivity due to having a full valence electron shell. Therefore, the correct response is:

the group with helium at the top
