Francium has the lowest 1st ionization energy. It badly wants to lose that electron. It is extremely energetically favorable. Basically the elements that are in group 1 and are in the lowest periods.
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.
The element with the smallest first ionization energy is Francium, as it is located in Group 1 of the periodic table and has the largest atomic size. Among the elements listed, lithium (Li) would have the smallest first ionization energy as it is closer to the upper right of the periodic table compared to sodium (Na), potassium (K), and rubidium (Rb).
Fluorine has the largest first ionization energy among the halogens.
Rb
The element with the highest first ionization energy in group 14 is carbon.
Aluminum has the smallest first ionization energy among the elements carbon, silicon, aluminum, and boron. This is because aluminum has more shielding effect from inner electron shells, making it easier to remove an electron from the outer shell compared to the other elements listed.
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.

Fluorine has the largest first ionization energy among the halogens.
T he smallest first ionization energyis for lithium.
Fluorine has the largest first ionization energy among the halogens.
The element with the largest first ionization energy is (a) Sb (antimony). It has the highest first ionization energy among the elements listed.
No, helium does not have the largest first ionization energy of all the elements. Helium actually has the highest first ionization energy of any element, due to its small atomic size and stable electron configuration.
Helium has the highest ionization energy.
Rb
The element with the highest first ionization energy in group 14 is carbon.
Helium and hydrogen have the smallest values for the first ionization energies. Helium has the lowest first ionization energy due to its stable electron configuration with a full outer shell, while hydrogen has a low ionization energy because it has only one electron in its outer shell.
