The screening effect of d -electrons is

The screening effect of dd -electrons is

Options

  1. AEqual to pp -electrons
  2. BMuch more than pp -electrons
  3. CSame as ff -electrons
  4. DLess than pp -electrons.

Correct answer

D. Less than pp -electrons.

Step-by-step solution

The screening effect of inner electron of the nucleus causes the decrease in ionization potential, therefore the order of the screening effect is fdd -electron is less than pp -electron.
