What is actinide contraction?

Answer» <p>Actinoid contractionis greater from element to element than lanthanoidcontraction. These 5f orbitals have a poorer shielding effect than 4f orbitals (in lanthanoids). </p><p>Thus, the effective nuclear charge experienced by electrons in valence shells in case ofactinoids is much more that that experienced by lanthanoids.</p> <p>thx bro</p>
