The ionization energies generally increase across a period. The jump in ionization energy between IES1S1P0 and IES1S0P1 indicates the removal of an electron from a filled s orbital to a partially filled p orbital. This occurs for the element in period 3 with a valence electron configuration of 3s2 3p3, which is phosphorus (P).
