Question

as the atoms of the elements in group 1 are considered in order from top to bottom, compared to the ionization energy of the atom above it, the ionization energy of each successive atom

Answer 1

The ionization energy of atoms in Group 1 decreases as we go down the group.

Step-by-step explanation:

The ionization energy of the atoms in Group 1, when considered in order from top to bottom, decreases as we go down the group. This trend can be explained by the fact that the valence electrons get further away from the nucleus as you move down the group, experiencing less pull towards the nucleus. Therefore, it becomes easier to remove an electron from each successive atom in Group 1.

Answer 2

Increasing radius and increasing shielding effect.
