well... since theionization energy is bigger at the top right of the Periodic Table, then Helium(He) is the element which has the highest ionization energy. Whereas Francium(Fr) has the lowest ionization energy, because it's located at the most bottom left of the periodic table.

∙ 13y agoSince noble gases have completely filled Configuration of atoms(i.e. 2,8,8) It's tough for removing the valence atom... Due to this reason they have more ionisation energy and require more energy to remove the valence(outermost) electrons...

Which noble gas has the lowest ionization energy?
Among the noble gases, radon has the largest size and hence will have the lowest ionisation energy
Does the first ionization energy increase or decrease from top to bottom for the noble gas family?
The first ionization energy decrease from top to bottom for the noble gas family.
General electronic configuration of group having low ionisation energy?
The general electron configuration of the group having the lowest ionization energy is [Noble gas configuration]xs1. In this case, x is the principal quantum number of the valance electron. The noble gas configuration may either be written out in full or denoted by the noble gas' atomic symbol in brackets (ie [Ne]).
Which elements has the highest ionization energy?
Helium (He) has the highest ionization energy, then Neon (Ne) Ionization energy increases as you go across a period from left to right. Ionization energy decreases as you go down a group. Therefore, elements in the upper right of the periodic table have the highest ionization energy.
What energy is needed to remove an electron from its outer most shell?
This is called the ionization energy and an is different for each electron in the atom. Electrons in the outer shell (furthest from the nucleus) have the lowest ionization energy, electrons in the innermost shell (closest to the nucleus) have the highest ionization energy.
Which noble gas has the lowest ionization energy?
Among the noble gases, radon has the largest size and hence will have the lowest ionisation energy
Does the first ionization energy increase or decrease from top to bottom for the noble gas family?
The first ionization energy decrease from top to bottom for the noble gas family.
What has the largest ionization energy in period 4?
The noble gas, krypton

Which element's second ionization energy level is large compared to its first ionization energy?
Cl
Which elements has the highest ionization energy?
Helium (He) has the highest ionization energy, then Neon (Ne) Ionization energy increases as you go across a period from left to right. Ionization energy decreases as you go down a group. Therefore, elements in the upper right of the periodic table have the highest ionization energy.
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
What energy is needed to remove an electron from its outer most shell?
This is called the ionization energy and an is different for each electron in the atom. Electrons in the outer shell (furthest from the nucleus) have the lowest ionization energy, electrons in the innermost shell (closest to the nucleus) have the highest ionization energy.
What is the periodic trends in ionization energy?
The ionization energy increases because the energy required to remove a valence electron will increase. The atoms want to keep their valence electrons because as you move more towards the right of the Periodic Table towards the noble gases. To write an abbreviation for electron configuration, it requires a noble gas and the valence electron configuration.
Which noble gas has the least number of protons?
Radon (as down a group, the atomic size increases and the ionization energy decreases)
The element in period 3 that has the highest ionization energy is?
Argon (#18). It's a noble gas, which means it doesn't react, which means it will be really hard to get it to lose an electron.
Why does fluorine has higher ionization energy than neon?
because neon is a noble gas which has stable electronic configuration ,but this is not the same in case of fluorine.This means we have to give high energy to gaseous neon atom to ionise it.
