first Ionisation energy is 1681 kJ/mol = 402.15 Kcal/mol
it is high because of the F electron configuration will be 1s22s22p5
In the periodic table of elements, fluorine and iodine are in the same column, but fluorine is in the second, iodine in the fifth row. That means fluorine has only nine electrons flying around in orbitals while iodine has 53 of them. Ionization is the called a process during which a single electron is abstracted - we're now talking about the 1st ionization energy, which is much higher for fluorine. Well, as it only has nine electrons scattered in the orbitals (but according laws, of course), they do not really influence the repelling - attracting actions between the positive center and the other electrons beside them. For iodine with 53 electrons, they really do interfere with the attraction of other electrons AND as the outmost electrons (which are the ones taken away by ionization) are in those orbitals which are at the biggest distance to the center - for 53 electrons the outmost orbitals is at a much bigger distance... both results in a smaller attraction of the electrions at max distance from the center... so for iodine you need less energy to perform ionization.
The second ionization energy of sodium is so much greater than the first because the first electron is removed from the valence shell, while the second electron is removed from the core orbitals. Additionally, the sodium atom has a positive charge after the first ionization, which thus attracts the remaining electrons more strongly. Both of these factors lead to a much higher second ionization energy compared to the first.
The electronegativity of fluorine is 3.98, making it the most electronegative element on the Pauling scale. This means that fluorine has a high affinity for electrons in a chemical bond.
Fluorine is obtained through the electrolysis of a mixture of hydrogen fluoride and potassium fluoride. The process involves passing an electric current through the mixture to break down the chemical bonds and separate the fluorine gas from the other elements. It is a complex and energy-intensive process due to the high reactivity of fluorine.
The only possible ion of fluorine is: F-It's called a fluoride ion.

Potassium has a low ionization energy.

Fluorine has a higher ionization energy than neon because fluorine has one less electron shell than neon, resulting in a stronger attractive force between the nucleus and the outermost electron. Additionally, fluorine's smaller atomic size leads to greater electron-electron repulsions, making it more difficult to remove an electron from fluorine compared to neon.
The relationship between radium and its ionization energy is that radium has a high ionization energy. This means that it requires a lot of energy to remove an electron from a radium atom.
low ionization energy
Yes, oxygen has a relatively high ionization energy because it requires a large amount of energy to remove an electron from an oxygen atom due to its stable electron configuration.
No, atoms with high ionization energy require more energy to remove an electron, making it difficult for them to lose an electron easily. The ionization energy is a measure of the stability of an atom and its tendency to lose an electron.
Chlorine, Cl. Elements with the most ionization energy are located at the top right corner of the periodic table. As you travel down a period the ionization energy increases, whereas travelling down a group the ionization energy decreases.
They have high ionization energy and high electronegativity.
Elements in the top right corner of the periodic table tend to have the largest first ionization energies. This includes elements such as helium, neon, and fluorine. They have a strong attraction for their valence electrons due to their small atomic size and high effective nuclear charge.
