Rb
The energy required for an element to ionize and helium has the lowest.
the lowest ionization energy in IA :hydrogen ,lithiun ,sodium and potassium
Ionization energy is the energy required to remove an electron from a gaseous atom or ion. The element with the highest ionization energy is helium (He), due to its small atomic size and strong nuclear charge. In contrast, cesium (Cs) has one of the lowest ionization energies, as its larger atomic radius and increased electron shielding make it easier to remove an outer electron.
There is no relation ship. They have the lowest ionization energies.
Noble gases have the lowest ionization energy. This is because noble gases have full valence shells, making it difficult to remove electrons from them.
The energy required for an element to ionize and helium has the lowest.
Helium has the highest ionization energy due to its stable electron configuration, requiring a lot of energy to remove an electron. In contrast, francium has the lowest ionization energy because it is the least electronegative element and its outer electron is the furthest from the nucleus, making it easier to remove.
Sodium (Na) has the lowest first ionization energy in period 3.

Among the given elements, neon has the lowest ionization energy. It is in Group 18 (Noble Gases) of the periodic table, and noble gases have the highest ionization energies due to their stable electron configurations.
Sodium has the greatest ionization energy of the four elements listed from column 1 of a wide form periodic table. Among this group of metals that readily form cations, the largest always has the lowest ionization energy and the smallest has the most. This is generally ascribed to the fact that the valence shell electron is further from the nucleus in the largest element and nearest in the smallest element.
There is no relation ship. They have the lowest ionization energies.
Elements in the alkali metal group (Group 1) have the lowest first ionization energy within any periodic table. This is because they have a single electron in their outermost shell, which is easier to remove compared to other elements. Sodium and potassium are examples of alkali metals.
Noble gases have the lowest ionization energy. This is because noble gases have full valence shells, making it difficult to remove electrons from them.
strontium
Na, sodium, should have the lowest first ionization energy of those four elements.
The lowest first ionization energy is found in francium, the element with the highest atomic number. Francium has the lowest ionization energy because the outermost electron is held the weakest due to the large atomic size and shielding effects.
