hydrogen has only one electron so after you remove that electron you do not have any electrons left to remove so hydrogen doesn't have a 2nd ionization energy. hydrogen has 1 proton and 1 electron.
Krypton has a higher value.
Halogens, specially fluorine
The elements of the first period are hydrogen and helium. The trend for ionization energy is to increase left to right across the same period, so helium's ionization energy is higher. Which makes sense, because helium has a full 1s-level, meaning it doesn't need to react. Hydrogen, on the other hand, is very reactive, which is why we stick it in group 1.
Core electrons. Probably the 1s level would require the most ionization energy to pull these electrons.

Beryllium is the group 3A element with the highest ionization energy.
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.
The element zeff, also known as effective nuclear charge, is the net positive charge experienced by an electron in an atom. A higher zeff generally leads to higher ionization energy, which is the energy required to remove an electron from an atom. This means that as the zeff increases, the ionization energy also tends to increase.
Ionization energy is the energy required to remove an electron from an atom. It can provide information about an element's reactivity and ability to form ions. Lower ionization energy indicates easier removal of electrons and greater reactivity, while higher ionization energy means more energy is needed to remove electrons, indicating lower reactivity.
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
Ionization energy is the amount of energy needed to remove an electron from an atom. Elements with higher ionization energy are less likely to lose electrons and therefore are less reactive. Conversely, elements with lower ionization energy are more likely to lose electrons and are more reactive.
The highest energy photon that can be absorbed by a ground-state hydrogen atom without causing ionization is the photon energy equivalent to the ionization energy of hydrogen, which is approximately 13.6 electron volts. This is the energy required to completely remove the electron from the atom. Any photon with higher energy would cause ionization of the hydrogen atom.
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.
No, fluorine has a higher ionization energy than chlorine. Fluorine is the most electronegative element in the periodic table, meaning it has a strong attraction for electrons and therefore requires more energy to remove an electron compared to chlorine.
