As element of group 1 on the periodic table are considered in order of increasing atomic radius, the ionization energy of each successive element generally, a. decreases b. remains the same c. increases

As the atomic radius increases, the ionization energy of the elements ; ( A )

As we move across the periods in the periodic table ,the ionization energy of the elements increases relatively, while as we go down the Groups in the periodic table the atomic radius increases while the ionization energy decreases as well.

Therefore the elements of group 1 on the periodic table will experience a decrease in ionization energy as we go down the group.

Hence we can conclude that as the atomic radius increases, the ionization energy of the elements will decreases.

The ionization energy of each successive element generally decreases

Explanation:

The ionization energy increases in the periods of the periodic table and decreases in the groups. If the atom is very small, we will need a lot of energy to release the electron, while if the atom is larger the energy will be greater.
