Taking into account the definition of ionization energy, the atoms in order of increasing first ionization energies will be: Rb, Mg, B, N, F
Electrons are held in atoms by their attraction to the nucleus, which means that energy is needed to remove an electron from the atom.
Ionization energy, also called ionization potential, is the necessary energy that must be supplied to a neutral, gaseous, ground-state atom to remove an electron from an atom. When an electron is removed from a neutral atom, a cation with a charge equal to +1 is formed.
The further away the electron is from the nucleus, the easier it is to remove it, that is, the less energy is needed.
In a group, the ionization energy increases upwards because when passing from one element to the bottom, it contains one more layer of electrons. Therefore, the valence layer electrons, being further away from the nucleus, will be less attracted to it and it will cost less energy to remove them.
In the same period, in general, it increases as you shift to the right. This is because the elements in this way have a tendency to gain electrons and therefore it will cost much more to tear them off than those on the left which, having few electrons in the last layer will cost them much less to lose them.
This can be summed up by saying that the ionization energy is minimal for alkali metals that have a single electron outside a full layer. It usually increases in each row of the periodic table, with the maximum in the noble gases that have complete layers.
Taking into account the above in mind, the atoms in order of increasing first ionization energies will be: Rb, Mg, B, N, F
