    ANSWER  In the 5d-series of transitions elements, after lanthanum (La), the added electrons go to the next inner 4f orbitals. The 4f electrons have poor shielding effect. As a result, the outermost electrons experience greater nuclear attraction. This leads to higher ionisation energies for the 5d- series of transition elements.

    option A & B is correct...this is due to relatively small size of the atoms(lanthanide contractions) and smaller screening effect

    sir here answer is a and b

    eduncle-logo-app

    shib these all are multiple select question??

    eduncle-logo-app

    Here main factor is size factor due to lanthanide contraction...and also you know the shielding effect of 4f orbital is poor so it screen less...so here you can also say relatively smaller screening effect...
