Question

The screening effect of inner electrons of the nucleus causes a- decreases in the ionization enthalpy b- increase in ionization enthalpy c-no effect on the ionization enthalpy d- increases the attraction of the nucleus for the electrons

Answer 1

Explanation:

c-no effect on the ionization enthalpy. d- increases the attraction of the nucleus for the electrons. ... As the screening effect increases, the attraction of nucleus towards outermost electron decreases. Hence it is easy to remove outermost electron so, ionizations energy decreases
