What are inner-transition elements ? Decide which of the following atomic numbers are the numbers of the inner-transition elements : 29, 59, 74, 95, 102, 104.

Text Solution

Verified by Experts

The f-block elements, i.e., in which the last electron enters into f-subshell are called inner-transistion elements. These include lanthanoids (58 - 71) and actinoids (90 - 103). Thus, elements with atomic numbers 59, 95 and 102 are inner - transition elements.
