Question

what is screening effect and how does it govern the ionization enthaly in the periodic table?​

Answer 1

Answer:

as the screening effect increases the effectiveness nuclear charge decrease . The force of attraction by the nucleus for valence shell electrons decreases and hence the ionisation enthalpy decreases.As increase in the number of electrons in the inner shells tends to decrease the ionization enthalpy.
