Question
Which statement about the first ionisation energies of magnesium and neon is correct?13Magnesium has the greater numerical value and both are endothermic.AMagnesium has the greater numerical value and both are exothermic.BNeon has the greater numerical value and both are endothermic.CNeon has the greater numerical value and both are exothermic.
Solution
The correct statement is "Neon has the greater numerical value and both are endothermic."
Here's why:
-
Ionization energy is the energy required to remove an electron from an atom or ion. It is always an endothermic process because energy is required to overcome the electrostatic forces holding the electron in the atom. So, both magnesium and neon have endothermic ionization energies.
-
Neon has a greater first ionization energy than magnesium. This is because neon has a full outer shell of electrons, making it very stable and requiring a lot of energy to remove one of these electrons. On the other hand, magnesium has only two electrons in its outer shell, so it requires less energy to remove one.

The difference between the first and second ionization energies for magnesium is approximately 700 kJ/mol. The difference between the second and third ionization energies will likely be:A.higher because the first and second ionization energies remove electrons from the p orbitals whereas the third removes an electron from an s orbital.B.higher because the first and second ionization energies remove valence electrons whereas the third removes a core electron.C.lower because the first and second ionization energies remove spin-paired electrons whereas the third removes an electron that is not spin-paired.D.lower because the first and second ionization energies remove electrons from the n = 2 subshell whereas the third removes an electron from the n = 3 subshell.
