With each additional period, there is an additional energy level, which means that the outermost electrons are farther away from the nucleus of the atom. This means that the attractive force of the positively charged nucleus is less, so it takes less energy to remove an electron from an atom in the third energy level than it does from an atom in the second energy level. Therefore, the elements in the third period have lower ionization energies than elements in the second period.
electrons are closer to the nucleus, force between the nucleus and the electrons is greater, so it takes more energy to remove them.
because the metallic elements tend to lose electrons instead the nonmetals elements tend to gain electrons.
Because they have largest atomic size in their respective period so Ionization energy is lowest in the period.

Ionisation energies GENERALLY increase across a period. As a result, the noble elements (i.e. Group 0 elements) usually have the highest ionisation energies, as they are highly stable.
There is no relation ship. They have the lowest ionization energies.
The noble gases of each period have the highest ionization energies in their periods. Refer to the related link to see a graph showing the ionization energies of the elements across each period.
Fluorine because it is the furthest right on the periodic table. Do no include noble gases in energies.

In a group the ionization energy decrease when the atomic radius increase; in a period this relation is not generally valid.

increase from left to right across a period.
In the first period, the ionization energy increases from left to right across the period. Therefore, the electrons on the right side of the first period (e.g., helium, neon) have higher ionization energies compared to the electrons on the left side (e.g., hydrogen, lithium).
The elements in the lower right part of the Periodic Table. Cs, Fr, Ra, Ba etc.
Helium (He) has the highest ionization energy, then Neon (Ne) Ionization energy increases as you go across a period from left to right. Ionization energy decreases as you go down a group. Therefore, elements in the upper right of the periodic table have the highest ionization energy.
