Fluorine has the largest first ionization energy among the halogens.


What elements have the largest first ionization energy?

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.


What do the elements in the first comlumn of the periodic table have in common when ionized?

They all lose an electron each and so carry a charge of +1.


Which of the elements sodium calcium potassium and magnesium has the smallest first ionization energy?

Potassium has the smallest first ionization energy among those elements listed. This is because potassium has the largest atomic size and the weakest attraction between its nucleus and outermost electron, making it easier to remove that electron.


If the first energy level is complete with two electrons then what has two elements?

If the first energy level is complete with two electrons, then the elements hydrogen and helium have two elements in their electron configuration. Hydrogen has one electron in its first energy level, while helium has two electrons filling its first energy level.

Helium has the highest ionization energy.


What element has the largest first ionization energy Sb Se Cl or Pb?

Chlorine (Cl) has the largest first ionization energy among the elements listed (Sb, Se, Cl, and Pb). Ionization energy tends to increase across a period and decrease down a group in the periodic table. Since Cl is located in the second period and is further right compared to the others, it has a higher ionization energy than antimony (Sb), selenium (Se), and lead (Pb).
