Question

Why are the noble gases the least reactive elements? (1 point) Responses They have a full valence electron shell. They have a full valence electron shell. They are the most electronegative elements. They are the most electronegative elements. They have an empty inner electron shell. They have an empty inner electron shell. They are the elements with the smallest atomic mass.

Answer 1

The correct response is: They have a full valence electron shell.

Noble gases have a complete outer shell of electrons, which makes them very stable and less likely to react with other elements.
