the lowest ionization energy in IA :hydrogen ,lithiun ,sodium and potassium
Alkali metals.
The energy required for an element to ionize and helium has the lowest.
Metals have the least ionization energy
Rb
There is no relation ship. They have the lowest ionization energies.
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.
The energy required for an element to ionize and helium has the lowest.
Metals have the least ionization energy
Sodium
Francium in group 1 has the lowest first ionization energy.
Rb
lithium
Helium has the highest first ionization energy and francium has the lowest first ionization energy.
Cesium (Cs)
Francium (Fr) has the lowest Ionization potential.
Lithium has the least number of protons, rubidium has the most number of protons.
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.
