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.

What elements don't follow the trend for ionization energy?
There are two main elements that do not follow the trend for ionization energy. Those two elements are both Boron and Oxygen.
Why does germanium have a higher first ionization energy than Gallium?
Germanium has a higher first ionization energy than gallium because germanium has a smaller atomic size and higher effective nuclear charge, making it more difficult to remove an electron from germanium compared to gallium. This results in a higher energy requirement to remove the outermost electron in germanium, leading to a higher first ionization energy.
Why is the ionization energy of br lower than that of cl but higher than that of se?
The ionization energy of an element is influenced by its atomic structure and the ease with which electrons can be removed. Bromine (Br) has a higher ionization energy than chlorine (Cl) because it is located further away from the nucleus, resulting in less shielding and higher attraction for its outermost electron. Selenium (Se) has a lower ionization energy than bromine because it is in a higher energy level, making its outermost electron easier to remove.
Why is the first ionization energy of krypton greater than selenium?
The first ionization energy of krypton is greater than that of selenium because krypton is a noble gas with a full valence shell, making it more stable and harder to remove an electron from compared to selenium, which is a nonmetal and has an incomplete valence shell. This results in a higher ionization energy for krypton.
Does fluorine have a higher ionization energy than bromine?
yes because ionization energy increases up and to the left on the periodic table. and fluorine has the highest ionization energy because it is so close to becoming a noble gas it tears off electrons from everything to complete the octete
Which element has a higher first ionization energy than chlorine Cl?
The element with a higher first ionization energy than chlorine Cl is fluorine F. Fluorine is located to the left of chlorine in the periodic table, which means it has a smaller atomic radius and stronger nuclear attraction, requiring more energy to remove an electron.
What elements don't follow the trend for ionization energy?
There are two main elements that do not follow the trend for ionization energy. Those two elements are both Boron and Oxygen.
How does calcium first ionization energy compare to the first ionization energy of magnesium and potassium?
Calcium's first ionization energy is lower than that of magnesium but higher than that of potassium. This is due to the increasing atomic size down the group, which decreases the effective nuclear charge felt by the outermost electron. Magnesium, being higher in the group, has a smaller atomic radius and a stronger attraction between the nucleus and its valence electron, resulting in a higher ionization energy. Conversely, potassium, being further down the group, has an even larger atomic radius, leading to a lower ionization energy than calcium.
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 germanium have a higher first ionization energy than Gallium?
Germanium has a higher first ionization energy than gallium because germanium has a smaller atomic size and higher effective nuclear charge, making it more difficult to remove an electron from germanium compared to gallium. This results in a higher energy requirement to remove the outermost electron in germanium, leading to a higher first ionization energy.
What element has a higher first ionization energy than carbon c?
Oxygen (O) has a higher first ionization energy than carbon (C). This is because oxygen has a greater effective nuclear charge and a smaller atomic radius, making it more difficult to remove an electron. The first ionization energy of oxygen is approximately 1314 kJ/mol, while that of carbon is about 1086 kJ/mol.
Does Sulfur has a lower ionization energy than chlorine?
No, sulfur has a higher ionization energy than chlorine. Ionization energy is the energy required to remove an electron from an atom, and it generally increases across a period from left to right. Chlorine, being to the right of sulfur in the periodic table, has a higher ionization energy.
Which element has a lower first ionization energy than aluminum?
As an example potassium has a lower first ionization energy than aluminum (Al).
Which has higher first ionization energy aluminum or sodium?
Aluminum has a higher first ionization energy than sodium. This is because aluminum is located further to the right in the periodic table, where elements generally have higher ionization energies due to increased nuclear charge and the effective nuclear attraction on electrons. Sodium, being an alkali metal, has a lower ionization energy as it has a single electron in its outer shell that is more easily removed.
Why is the ionization energy of br lower than that of cl but higher than that of se?
The ionization energy of an element is influenced by its atomic structure and the ease with which electrons can be removed. Bromine (Br) has a higher ionization energy than chlorine (Cl) because it is located further away from the nucleus, resulting in less shielding and higher attraction for its outermost electron. Selenium (Se) has a lower ionization energy than bromine because it is in a higher energy level, making its outermost electron easier to remove.
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.
Why is the first ionization energy of krypton greater than selenium?
The first ionization energy of krypton is greater than that of selenium because krypton is a noble gas with a full valence shell, making it more stable and harder to remove an electron from compared to selenium, which is a nonmetal and has an incomplete valence shell. This results in a higher ionization energy for krypton.
