To match the elements with the same number of valence electrons, we can identify the valence electron counts for each element:
- Carbon (Group 14) has 4 valence electrons.
- Hydrogen (Group 1) has 1 valence electron.
- Oxygen (Group 16) has 6 valence electrons.
- Helium (Group 18) has 2 valence electrons.
Now, let's look at the valence electron counts for the elements you provided:
- Potassium (Group 1) has 1 valence electron.
- Silicon (Group 14) has 4 valence electrons.
- Sulfur (Group 16) has 6 valence electrons.
- Neon (Group 18) has 8 valence electrons.
Now we can match them accordingly:
- Carbon - Silicon (both have 4 valence electrons)
- Hydrogen - Potassium (both have 1 valence electron)
- Oxygen - Sulfur (both have 6 valence electrons)
- Helium - Neon (both have 2 valence electrons)
So the completed matches are:
- Carbon - Silicon
- Hydrogen - Potassium
- Oxygen - Sulfur
- Helium - Neon
