The noble gases are unreactive and stable. Which of the following explains why this is true?
They each have no electrons.
They have 8 electrons in their outer shell (except for Helium).
They have only neutrons in their nucleus
They have more electrons than other elements.

Answer 1

They have 8 electrons in their outermost shell(except for Helium)
