Question

in groups from top to the bottom,ionization potential____
​

Answer 1

Answer:

The ionization energy of the elements within a period generally increases from left to right. This is due to valence shell stability. The ionization energy of the elements within a group generally decreases from top to bottom. This is due to electron shielding.

Answer 2

The ionization energy of the elements within a group generally decreases from top to bottom. This is due to electron shielding.
