Lanthanoids and actinoids are f-block elements in which the last electron enters the anti-penultimate energy level. The most common oxidation state of lanthanoids is +3, though +2 and +4 oxidation states are exhibited by some of the elements. In lanthanoid series, there is a progressive decrease in atomic and ionic radii, known as lanthanoid contraction. Unlike lanthanoids, actinoids show a large number of oxidation states.
Which out of` La(OH)_3` and `Lu(OH)_3` is more basic?

Text Solution

AI Generated Solution

To determine which of La(OH)₃ (lanthanum trihydroxide) or Lu(OH)₃ (lutetium trihydroxide) is more basic, we need to consider the factors affecting the basicity of these compounds, particularly focusing on the size of the metal ions and their effective nuclear charge. ### Step-by-Step Solution: 1. **Identify the Elements**: - La(OH)₃ is derived from lanthanum (La), which has an atomic number of 57. - Lu(OH)₃ is derived from lutetium (Lu), which has an atomic number of 71. ...
