Which has more ionization energy phosphorus or chlorine?
Chlorine has a higher ionization energy than phosphorus because chlorine has a smaller atomic radius than phosphorus. Chlorine has a greater nuclear charge when compared to phosphorus.
Which element has the greatest ionization energy aluminum or chlorine?
Chlorine has higher first ionization energy than aluminum. Aluminum has three valence electrons and one electron is present in p orbital while chlorine atom contains seven valence electrons among which five are present in p-orbitals.
Does phosphorus or magnesium have a higher ionization energy?
First ionisation energy
| Element | Symbol | First ionisation energy /kJ mol–1 |
|---|---|---|
| magnesium | Mg | 738 |
| aluminium | Al | 578 |
| silicon | Si | 789 |
| phosphorus | P | 1012 |
Which has a higher ionization energy magnesium or aluminum?
So the extra amount of protons means the nucleus holds the outer electrons more strongly so it requires more energy to remove an electron. Aluminium has a lower ionisation energy than Magnesium. This is unexpected as Al has more protons. This can be explained by electron configurations.
What is the ionization energy of magnesium?

Which elements have the highest ionization energy?
The elements that belong to the noble gases or inert gases or (Group VIII-A) have the highest ionisation energy. If we were to take a single element then Helium is said to have the highest first ionization energy among all the other neutral elements. The ionization potential is said to be 24.5874 eV.
What is the ionization energy of chlorine?
The elements of the periodic table sorted by ionization energy

| 13,5984 | Hydrogen | 1 |
| 13,6181 | Oxygen | 8 |

What is the ionization energy of phosphorus?
This is the energy per mole necessary to remove electrons from gaseous atoms or atomic ions. The first molar ionization energy applies to the neutral atoms….1st–10th ionisation energies.
| Number | 15 |

Why ionisation energy of magnesium is higher than Aluminium?
If we compare the ionization energy between magnesium and aluminium, the magnesium has greater ionization energy as it has less no of shells which are closer to the nucleus. Al has one unpaired electron in it’s highest energy orbital (3p), and Mg’s highest energy orbital (3s) the electrons are paired.
