To match the elements with the correct number of valence electrons based on their group in the periodic table, we can use the following information:

  • Sulfur (S): Group 16 - 6 valence electrons
  • Strontium (Sr): Group 2 - 2 valence electrons
  • Phosphorus (P): Group 15 - 5 valence electrons
  • Krypton (Kr): Group 18 - 8 valence electrons
  • Fluorine (F): Group 17 - 7 valence electrons
  • Boron (B): Group 13 - 3 valence electrons

Now, we can match them with the number of valence electrons:

  • 1 valence electron: (none of the listed elements)
  • 2 valence electrons: Strontium (Sr)
  • 3 valence electrons: Boron (B)
  • 4 valence electrons: (none of the listed elements)
  • 5 valence electrons: Phosphorus (P)
  • 6 valence electrons: Sulfur (S)
  • 7 valence electrons: Fluorine (F)
  • 8 valence electrons: Krypton (Kr)

Here's the final matching:

  • 2: Strontium (Sr)
  • 3: Boron (B)
  • 5: Phosphorus (P)
  • 6: Sulfur (S)
  • 7: Fluorine (F)
  • 8: Krypton (Kr)

If you need to place these in specific locations, you can take this information to input them accordingly.
