Question 39

Which element has a higher ionization energy, Mg or P? Why?

Accepted Answer

P, it has more protons and a more effective nuclear charge. This requires more energy to remove an electron

Answer

Mg, it has more energy levels and a larger radius. Therefore more energy is required to remove an electron

Answer

P, it has more energy levels and a larger radius. Therefore more energy is required to remove an electron

Answer

Mg, it has more protons and a more effective nuclear charge. This requires more energy to remove an electron

Answer

They both have the same ionization energy

Answer

Na, it has more protons (with similar shielding) and a more effective nuclear charge

Answer

Cs, it has more protons (with similar shielding) and a more effective nuclear charge

Answer

They both have the same ionization energy
