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.

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.
Among silicon, aluminum, carbon, and boron, aluminum has the smallest first ionization energy. This is because ionization energy generally decreases down a group in the periodic table, and aluminum is located lower in the periodic table compared to the others. Additionally, aluminum's valence electron is further from the nucleus, making it easier to remove compared to the other elements listed.
Helium has the highest ionization energy.
Rb
The element with the smallest first ionization energy is cesium (Cs). This is because ionization energy tends to decrease down a group in the periodic table, and cesium is located at the bottom of Group 1 (alkali metals). Its large atomic size and the shielding effect of inner electrons make it easier to remove the outermost electron. Thus, cesium requires the least amount of energy to ionize compared to other elements.
