Hey mate!!!
➖▶️ Along the series, the nuclear charge and no. of 5f electrons increases by one unit. However, due to imperfect shielding of 5f orbitals, the effective nuclear charge increases which results in contraction of the size. Actinide contraction is greater from element to element than in lanthanide contraction.
