Question

Describe lanthanoid contraction. Write any two consequences of it.

Answer 1

Explanation:

Consequences of lanthanides. As the atomic size increases, the basicity of oxides and hydroxides decreases. Due to lanthanide contraction, there is decrease in the size of lanthanide cations that increases the polarizing power of cations. That further increase the covalent character of the oxide and hydroxides.

Answer 2

Explanation:

Consequences of lanthanides. As the atomic size increases, the basicity of oxides and hydroxides decreases. Due to lanthanide contraction, there is decrease in the size oflanthanide cations that increases thepolarizing power of cations. That further increase the covalent character of the oxide and hydroxides.
