What is the second ionization energy of phosphorus?
PHOSPHORUS
| First ionization energy / kJ mol-1: | 1011.82 |
|---|---|
| Second ionization energy / kJ mol-1: | 1907.47 |
| Third ionization energy / kJ mol-1: | 2914.14 |
Why does phosphorus have a high ionization energy?
Either all unpaired or all paired makes it stable, so if phosphorus is all unpaired it take more energy to remove an electron than it would from sulfur in which one electron can be removed making it more stable. Because it takes more energy for phosphorus, it has a higher ionization energy.

Why is there a decrease in ionization energy from P to S?
While in phosphorus there are 2 paired electrons and 1 lone electron in the 3p level. Due to the electron repulsion of the paired electrons in sulfur, less energy is required to remove 1 mole of electrons from its sub-level, as there is less of an attraction of these electrons towards its nucleus.
Does P or Se have higher ionization energy?
Since the 3p electrons in sulfur (that sulfur would lose) are paired, sulfur has more electron repulsion in those orbitals than phosphorus does, so it takes less energy input to remove an electron from sulfur. Hence, since the ionization occurs more easily, the ionization energy is smaller.
How do you find the ionization energy of a photoelectron?
PES involves a given energy of photon to ionize a molecule. As the excess energy, will be in the form of kinetic energy, is calculated by the photoelectron spectrometer it is possible to calculate ionization energy of a molecule, by rearranging the following equation: Ek=hν−EI, to solve for EI, ionization energy.

Why the ionization energy of phosphorus is more than sulphur?
Solution : Phosphorus contains half-filled 3p orbitals, have extra stability. So, the removal of an electron from phosphorus atom requires more energy than sulphur.
Does phosphorus have a higher or lower first ionization energy than sulfur?
