Answer 1

I can’t see the table image you referenced. Could you upload it or type the values shown (atomic number, mass, electron configuration, number of protons/electrons, group/period, or valence electrons)?

Meanwhile, here are quick rules to identify which of the four it is:
- Nitrogen (N): atomic number 7, electron arrangement 2,5 (period 2, group 15).
- Silicon (Si): atomic number 14, electron arrangement 2,8,4 (period 3, group 14).
- Phosphorus (P): atomic number 15, electron arrangement 2,8,5 (period 3, group 15).
- Sulfur (S): atomic number 16, electron arrangement 2,8,6 (period 3, group 16).

If the table shows atomic number 15 or configuration 2-8-5, the answer is Phosphorus (P).
