Which elements have the same number of valence electrons

Answer 1

To determine which elements have the same number of valence electrons, we can look at their group in the periodic table:

1. Carbon (C) - Group 14, has 4 valence electrons.
2. Hydrogen (H) - Group 1, has 1 valence electron.
3. Oxygen (O) - Group 16, has 6 valence electrons.
4. Argon (Ar) - Group 18, has 8 valence electrons.

Continuing with the others: 5. Potassium (K) - Group 1, has 1 valence electron. 6. Silicon (Si) - Group 14, has 4 valence electrons. 7. Sulfur (S) - Group 16, has 6 valence electrons. 8. Neon (Ne) - Group 18, has 8 valence electrons.

Now, let's group them based on the number of valence electrons:

• 1 valence electron: Hydrogen (H), Potassium (K)
• 4 valence electrons: Carbon (C), Silicon (Si)
• 6 valence electrons: Oxygen (O), Sulfur (S)
• 8 valence electrons: Argon (Ar), Neon (Ne)

Elements with the same number of valence electrons:

• Hydrogen (H) and Potassium (K) - 1 valence electron
• Carbon (C) and Silicon (Si) - 4 valence electrons
• Oxygen (O) and Sulfur (S) - 6 valence electrons
• Argon (Ar) and Neon (Ne) - 8 valence electrons

These pairs all have the same number of valence electrons.
