Part A Element X has successive ionization energies of 738 kJ/mol, 1451 kJ/mol, and 7733 kJ/mol. Element Z has successive ionization energies of 1000 kJ/mol, 2252 kJ/mol, and 3357 kJ/mol. What are the possible identities of X and Z? O x could be Mg, since its third ionization energy is so large. Z could be S, since its ionization energies are large and keep going up in regular intervals. O x could be P, since the third ionization energy is so large. Z could be Na, since its ionization energies keep going up in regular intervals. O x could be Na, since the second and third ionization energies are so much larger than the first one. Z could be a noble gas, since its ionization energies are large and keep going up in regular intervals. O x could be Fe, since its third ionization energy is so large. Z could be H since its ionization energies keep going up in regular intervals. Submit Request Answer

Answer the following questions about first ionization energies. (a) Generally ionization energies increase on proceeding across a period, but this is not true for magnesium (738 kJ/mol) and aluminium (578 kJ/mol). Explain this observation.
