What are inner transition elements? Decide which of the following atomic numbers are the atomic numbers of the inner transition elements: $29,59,74,95,102,104$ .
Inner transition metals are those elements in which the last electron enters the $f$ -orbital. The elements in which the $4 f$ and the $5 f$ orbitals are progressively filled are called $f$ -block elements. Among the given atomic numbers, the atomic numbers of the inner transition elements are $59,95,$ and $102$.
The ability to form complex compounds by the transitional metal ion is due to
