Increase

There is an increase in Nuclear charge and no change in electron shielding

28
Q

What is the general trend moving across a period (to the right) for ionization on the periodic table? Why?

A

Increases

There is an increase in valence electrons, and an increase in nuclear charge and no change in electron shielding
