Question

explain the calculation of effective nuclear charge on 3d electron is scandium. ​

Answer 1

The 'electronic configuration' of Sc by Aufbau principle is . Here, is the 'effective nuclear' charge and Z is the atomic number and σ is the shielding factor. ... Thus, the effective nuclear charge for 4s and 3d electrons in Sc is 1.65 and 3 respectively.

Hope it helps.
