Ionization energy is how much energy is needed to remove an electron from the valence shell (the outermost shell). When the atomic radius is smaller, you will need more energy to remove an electron because the pull from the nucleus on the electron is stronger. If the atomic radius is larger, then it will be much easier to remove an electron from the valence shell because there are more layers (shieldings) between the nucleus and valence shell.
There is an inverse relationship between ionization energy and atomic radius: as atomic radius increases, ionization energy decreases. This is because as the distance between the nucleus and valence electrons increases, the attraction between them weakens, making it easier to remove an electron.
The trend in ionization energy generally increases across a period from left to right due to increasing nuclear charge. Within a group, ionization energy tends to decrease from top to bottom due to increasing atomic size.
there is an increase in atomic number and atomic size down the group due to addition of extra shells.this increase in the atomic size overcomes the effect of an increase in the nuclear charge.Therefore ionisation energy decreases with an increase in atomic size i.e.,it decreases as one moves down a group..
Ionization energy generally decreases as you move down a group in the periodic table. This is because as you move down a group, the outermost electrons are farther from the nucleus, resulting in weaker attraction and easier removal of electrons.
An increase in atomic radius leads to a lower ionization energy because the outermost electrons are farther away from the nucleus, which weakens the attraction between the electrons and the nucleus. This makes it easier to remove an electron, resulting in a lower ionization energy.

Ionization energy is a periodic function of atomic number because it follows periodic trends in the periodic table. As you move across a period from left to right, ionization energy generally increases due to increasing nuclear charge. Similarly, as you move down a group, ionization energy generally decreases due to increasing atomic size. These trends repeat as you move through each period, making ionization energy a periodic function of atomic number.
ionization energy
As you move down a column (group) in the periodic table, the electronegativity decreases, the ionization energy decreases, the electron affinity decreases, and the atomic radius increases.

The first ionization energy generally decreases from top to bottom in the alkali metal family. This is due to the increase in atomic size and the shielding effect from inner electrons, which makes it easier to remove the outermost electron.
Ionization energy generally decreases as you move down a group in the periodic table. This is because as you move down a group, the outermost electrons are farther from the nucleus, resulting in weaker attraction and easier removal of electrons.
As you move down a group on the periodic table, the first ionization energy generally decreases due to the increasing atomic size and shielding effect of inner electrons. Across a period, the first ionization energy generally increases because the effective nuclear charge increases, making it harder to remove an electron.
An increase in atomic radius leads to a lower ionization energy because the outermost electrons are farther away from the nucleus, which weakens the attraction between the electrons and the nucleus. This makes it easier to remove an electron, resulting in a lower ionization energy.
As one proceeds down the group 7A elements, the first ionization energy decreases. this means that the outermost electron is more readily removed as we go down a group.
An increase in atomic radius leads to a lower ionization energy because the outermost electrons are farther from the nucleus, experiencing weaker attraction, making it easier to remove them.
