Step 2:: Understand Valence Electrons
Valence electrons are the electrons in the outermost shell of an atom that participate in chemical bonding. For most main group elements, the goal is to achieve a stable electron configuration with 8 valence electrons (octet rule).
Step 3:: Determine Chlorine's Electron Configuration
- Note the $$3p^{5}$$ indicates it currently has 7 valence electrons
- Chlorine's atomic number is 17
Step 4:: Calculate Electrons Needed for Stability
- $$8 - 7 = 1$$ electron needed
- Chlorine needs 1 more electron to complete its octet (reach 8 valence electrons)
Step 5:: Identify the Correct Answer
By counting the electrons needed to reach a stable configuration, we can see that Chlorine needs 1 electron.
Final Answer
D. 7 (Chlorine needs 1 electron to become stable, which means it currently has 7 valence electrons)
