Even though both these gases are noble gases with inert configurations, He has higher
first ionization energy than Neon because it has smaller size than the Neon. Due to
smaller size the electrons are close to nucleus and thus the electrostatic force of attraction
is very large.
In the case of Ne, the electrostatic orce of attraction is high but not as large as He.
Thus, it is more difficult to remove electron from He than from Ne.

Why is ionization energy of phosphorus higher than that of oxygen?
yap
Which element has a lower first ionization energy than aluminum (Al)?
As an example potassium has a lower first ionization energy than aluminum (Al).
Which element P or Ca has the highest first ionization energy?
In general, ionization INCREASES as you move to the right and up in the periodic table, making P (Phosphorus) higher than Ca (Calcium).
Which element has a lower 1st ionization energy than aluminum?
The first level ionization energy oif aluminium is 577,5 kJ/mol.All alkali metals have lower values for the ionization energy.
Does sodium have the larger first ionization energy than potassium?
yes, it does
What element has the larger first ionization energy cesium or potassium?
Potassium has a higher ionization energy than cesium.
Which element has a higher first ionization energy than chlorine Cl?
Ionization energy decrease down the group.So in halogens,Fluorine has highest 1st ionization energy.
Why does boron have a higher ionization energy than fluorine?
Because fluorine's size is lower than that of iodine, it has a greater ionization energy than iodine. Fluorine, on the other hand, appears to have a smaller shielding effect. As a result, fluorine's nucleus attracts more valence electrons than iodine's.

Why does bromine have a higher ionization energy than selenium?
Bromine has the highest.
Why does F have a larger first ionization energy than O?
First ionization energy increases as u move from left to right,so oxygen comes first than florine which means when u pass oxygen to florine the ionization energy become more than it was in oxygen.
What is the relationship between elements and the periodic table and ionisation energy?
The relationship between atomic numbers and first ionization energies is that within the same period, as atomic number increases so does first ionization because as nuclear charge increases and atomic radius decreases, electrons become harder to remove. However, within the same group, the first ionization energy decreases as atomic number increases because of the added energy level, the electrons are farther from the nucleus and easier to remove.

The first level ionization energy oif aluminium is 577,5 kJ/mol.All alkali metals have lower values for the ionization energy.
Is it ionization energy is a periodic property?
Ionization energy generally increases across a period as a result of a higher nuclear charge, however there are some exceptions such as Boron which has a lower ionization energy than Beryllium (because it is in a P orbital), and Oxygen which has a lower ionization energy than nitrogen (Because ionization decreases the electron electron repulsion in its orbitals).
