They are the most electronegative elements.
They are the most electronegative elements.

They are the elements with the smallest atomic mass.
They are the elements with the smallest atomic mass.

They have an empty inner electron shell.

Answer 1

The correct response is:

They have a full valence electron shell.

Noble gases, which include helium, neon, argon, krypton, xenon, and radon, have a complete outer electron shell, making them stable and less likely to react with other elements.
