Do Beryllium and Sulfur make a good match?
Yes! Beryllium has 2 valence electrons, and Sulfur has 6!
No! Because they are both stable already!

Why are Neon, Argon, Krypton, etc. called noble gases?
Because they have a stable electron configuration.
Because they were discovered by kings and queens.
NGL, I don't see how Neon and Argon are all related.
I think they both have "N" in their names. Like "N"obel.
