Explanation:

First Question (Argon's Valence Electrons)

Argon (Ar) is a noble gas with an atomic number of 18. Its electron configuration is \(1s^2 2s^2 2p^6 3s^2 3p^6\). The outermost shell (valence shell) is the 3rd shell, which has \(2 + 6 = 8\) electrons. So the number of valence electrons in argon is 8.

Sulfur (S) has an atomic number of 16. Its electron configuration is \(1s^2 2s^2 2p^6 3s^2 3p^4\). The outermost shell (the 3rd shell) has \(2+4 = 6\) electrons. So the number of electrons in sulfur's outermost ring is 6.

Answer:

A. 8
