A neutral atom has the ground-state electron configuration [Ne] 3s² 3p⁴. Which element is it?
A.Sulfur
B.Silicon
C.Chlorine
D.Selenium
Explanation
Core Concept
Adding the electrons gives 10 + 2 + 4 = 16, and atomic number 16 identifies sulfur. The configuration also shows six valence electrons (3s² 3p⁴), matching sulfur's spot in Group 16. For neutral atoms, the electron total alone fixes the identity.
Correct Answer
ASulfur
