Question

which elements on the periodic table are the least reactive? (1 point)
o the group with helium at the top
o the group with hydrogen at the top
o the group with carbon at the top
o the group with fluorine at the top

Explanation:

The noble - gas group, with helium at the top, has a full outer electron shell. This makes them very stable and least reactive among the elements on the periodic table. Hydrogen is highly reactive, carbon can form many compounds due to its ability to bond in various ways, and fluorine is the most electronegative and highly reactive non - metal.

Answer:

the group with helium at the top
