Question

the ionization energies of the element of first transition series do not vary much with increasing atomic number ,explain​

Answer 1

Answer:

Explanation: The ionization energy increases due to increase in the nuclear charge with an atomic number at the beginning of the series. Gradually, the shielding effect of the added electrons also increases. This shielding effect tends to decrease the attraction due to the nuclear charge. These two opposing factors lead to a rather gradual increase in the Ionization energies in any transition series .
