the 1st ionization energy is 403.03 kJ/mol.. since it's oxidation state is +1, you don't normally take away more than one electron so the 2nd and 3rd ionization energies are much larger and don't usually matter
T he smallest first ionization energyis for lithium.
Element Rb (Rubidium) has the lowest ionization energy among Rb, Na, C, and F. This is because as you move down a group on the periodic table, the ionization energy typically decreases due to the increase in atomic size. Rubidium is located below sodium (Na) in the same group, so it has a lower ionization energy.
As you go down the group (any group), ionization energy decreases. So in terms of ionization energy, for the alkali metals, Lithium > Sodium > Potassium > Rubidium > Caesium > Francium
ionization potential energy. but remember the atom must be neutral .
Neon's ionization energy is 20.1397
I suppose that this trend is normal.

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).
As you go down the group (any group), ionization energy decreases. So in terms of ionization energy, for the alkali metals, Lithium > Sodium > Potassium > Rubidium > Caesium > Francium
The ionization energy of a rubidium atom is about 403 nm. Therefore, the maximum wavelength of light required to ionize a single rubidium atom would be higher than 403 nm.
Potassium has a low ionization energy due to its large atomic size and one electron in its outermost shell, making it easier to remove that electron.

No fire is not an ionization energy
Caesium has more electron levels than rubidium, because the electrons are further away the attraction between the outer electrons and protons in the nucleus is less. But that's not just the answer. There is also a thing called electron shielding, the negative charges, of the electrons in the energy levels closer to the nucleus, sort of repel the outer electrons so they can't get closer to the nucleus. Since the electrons are further away and have the attraction from the positively charged nucleus reduced, it takes less energy to break the attraction for caesium than rubidium.
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.
The energy needed for ionization is called ionization energy. It is the minimum amount of energy required to remove an electron from an atom or molecule in its gaseous state.
