Which group of elements has very high ionization energies and very low electron affinities?

Group 8 (noble gases) have the highest first ionization energy because they are already stable and don't want to lose any electrons. Ignoring the noble gases, however, group 7 halogens (F, Cl, Br, I, etc.) have the highest first ionization energy. That's because these elements have seven valence electrons, and they don't want to give up any electrons - they want another one!

∙ 11y agoThe trends for ionization energy and electronegativity on the Periodic Table are pretty much the same. If an element has high ionization energy, it's generally going to have high electronegativity. This results from the attraction between the nucleus (which is positive) and the number of electrons in the valence shell (which are negative.) So it may be a trick question. There really is no group with high ionization energies and low electronegativities.

What is successive ionization energies?
The energy required to remove more than one electron from atoms. After the first electron is removed, there is now a positive charge which is working against removing another electron. So successive ionization energies increase.
Which elements on periodic table have the highest ionization energies?
Helium (He) has the highest ionization energy.
What is trend in first ionization energies as one proceeds down the group 7A elements How this trends relates to the variation in atomic radii?
Ionization energies go down of course. This is because radii are becoming larger due to addition of electron levels. These farther from the nucleus electrons require less and less energy to liberate from the atom.
Which group of the periodic table has the elements with lowest first ionization energies?
1A Alkali Metals
What is the correlation of ionization energies to atomic radii for the elements?
In a group the ionization energy decrease when the atomic radius increase; in a period this relation is not generally valid.
What has the author Vladimir Ivanovich Vedeneev written?
Vladimir Ivanovich Vedeneev has written: 'Bond energies, ionization potentials and electron affinities' -- subject(s): Ionization, Chemical bonds, Chemical affinity 'Bond energies, ionization potenitals, and electron affinities' -- subject(s): Ionization, Chemical bonds, Chemical affinity
Do an atom's successive ionization energies increase regularly?
No, an atom's successive ionization energies do not increase regularly. The first ionization energy, which is the energy required to remove the outermost electron, is typically lower than the second ionization energy, which is the energy required to remove the second electron. The ionization energies generally increase as more and more electrons are removed from an atom. However, there can be irregularities due to factors such as electron-electron repulsion and electron shielding.

Why do group 1 elements have a low density?
The group one elements have the lowest ionization energies because of their large atomic size which makes the outermost electron only weekly held by the nucleus.
Why do noble gases not have listed ionization energies?
The noble gases of each period have the highest ionization energies in their periods. Refer to the related link to see a graph showing the ionization energies of the elements across each period.
Alkali metal and alkaline earth metal have how many ionization energies?
Alkali metals (group 1 elements) have one valence electron. Hence have one ionization energy Alkaline earth metals (group 2 elements) have two valence electron. Hence have two ionization energy
Which elements on periodic table have the highest ionization energies?
Helium (He) has the highest ionization energy.
Are there any trends to the periodic table?
Atomic Radii,Ionic Radii, First Ionization Energy,Second and Higher Ionization Energies, Electron Affinity.
What do successive ionization energies relate to?
The energy required to remove more than one electron from atoms.
What is the differences between first and second ionization energy?
The first ionization energy is the energy that is required in order to remove the first electron from an atom in the GAS phase, the second ionization energy is the energy required to remove the second electron from an atom in the GAS phase. Ionization energy will generally increase for every electron that is removed and increases from left to right in the periodic table and moving up the periods.
What is trend in first ionization energies as one proceeds down the group 7A elements How this trends relates to the variation in atomic radii?
Ionization energies go down of course. This is because radii are becoming larger due to addition of electron levels. These farther from the nucleus electrons require less and less energy to liberate from the atom.
Do an atom's ionization energies increase regularly?
No, you can see the big jumps in ionization energy when an electron comes from an inner level meaning it isn't a regular increase.
