Question

Which properties do the valence shells of every noble gas

have in common?
A. All electrons are paired.
lano
B. They are filled with electrons.
C. All electrons are unpaired.
D. They have exactly two electrons.

Answer 1

Answer: B.

Step-by-step explanation:

The valence shell is the outermost shell of an atom. All noble gases have a "full" valence shell, meaning they all have 8 electrons (except Helium). This makes these elements non-reactive (inert).
