Step 1:
I'll solve this problem step by step, following the specified LaTeX formatting guidelines:

Step 2:
: Identify the elements

- Carbon (C) is the central atom - Hydrogen (H) atoms are bonded to carbon

Step 3:
: Determine the valence electrons for Carbon

- Carbon has $$4$$ valence electrons in its neutral state
- Carbon is in Group 14 (4A) of the periodic table

Step 4:
: Determine the valence electrons for Hydrogen

- Hydrogen has $$1$$ valence electron in its neutral state
- Hydrogen is in Group 1 (1A) of the periodic table

Step 5:
: Calculate total valence electrons

- Total valence electrons: $$4 + (4 \times 1) = 8$$ valence electrons
- Each of the 4 hydrogen atoms contributes 1 valence electron

Final Answer

8 valence electrons are present in the CH^4 molecule.
