Step 1:I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2:: Determine the valence electrons for Silicon (Si)
- Number of valence electrons = $$4
- Silicon is in Group 14 (4A) of the periodic table
Step 3:: Determine the valence electrons for Potassium (K)
- Number of valence electrons = $$1
- Potassium is in Group 1 (1A) of the periodic table
Step 4:: Determine the valence electrons for Barium (Ba)
- Number of valence electrons = $$2
- Barium is in Group 2 (2A) of the periodic table
Step 5:: Determine the valence electrons for Neon (Ne)
- Number of valence electrons = $$8
- Neon is in Group 18 (8A) of the periodic table
Step 6:: Determine the valence electrons for Sulfur (S)
- Number of valence electrons = $$6
- Sulfur is in Group 16 (6A) of the periodic table
Final Answer
- Si (Silicon): 4 valence electrons - K (Potassium): 1 valence electron - Ba (Barium): 2 valence electrons - Ne (Neon): 8 valence electrons - S (Sulfur): 6 valence electrons
