Elements and their ionization energy
WebThis is because ionization energy generally increases as you move from left to right across a period in the periodic table, and decreases as you move down a group. Beryllium is … WebThe electron configuration for P is [Ne] 3s2 3p3. The electron configuration for S is [Ne]3s2 3p4. The energy required to move an electron from Al is less than that for Mg because it results in a filled 3s orbital. The energy required to remove an electron from S is less than that for P because it results in a half-filled 3p orbital.
