Question

1. noble gases have how many valence electrons (usually)?

a. 1
b. 2
c. 6
d. 8

Explanation:

Noble gases (except helium) typically have 8 valence electrons, following the octet rule, which gives them stability. Helium has 2, but the usual case for noble gases (like neon, argon) is 8. So the correct option is D.

Answer:

D. 8
