The period an element is in affects the ionization energy because as you move across a period from left to right, the number of protons in the nucleus increases, leading to a stronger attraction between the nucleus and the electrons in the outer shell. This increased attraction makes it harder to remove an electron, resulting in higher ionization energy.
The element that has a lower first ionization energy than aluminum (Al) is magnesium (Mg). Magnesium is one period above aluminum on the periodic table, and as you move down a group or family, the ionization energy tends to decrease.
Please provide the specific ionization values you are referring to so I can accurately identify the third period element.
Argon (#18). It's a noble gas, which means it doesn't react, which means it will be really hard to get it to lose an electron.

The element in the fifth period with the highest ionization energy is xenon. Ionization energy generally increases across a period from left to right, so xenon, being on the far right of the period, has the highest ionization energy.
There is no relation ship. They have the lowest ionization energies.

The correct arrangement of selenium (Se), chlorine (Cl), and sulfur (S) in order of increasing ionization energy is S < Se < Cl. Ionization energy tends to increase across a period and decrease down a group in the periodic table. Since Cl is in the same period as S and Se but further to the right, it has the highest ionization energy. Sulfur, being below and to the left of chlorine and selenium, has the lowest ionization energy of the three.
The element with the largest ionization energy in period 4 is argon. Argon has a full outer electron shell with 8 electrons, making it stable and more difficult to remove an electron compared to other elements in the same period.
Ionization energy increases as you go across a period, but as you go down a group it decreases.
Argon (#18). It's a noble gas, which means it doesn't react, which means it will be really hard to get it to lose an electron.
The trend in period 2 ionization energy across the elements increases from left to right.
Moving from left to right across a period, the first ionization energy increases because it becomes increasingly difficult to remove an electron.
