f-block elements Actinides and lanthanides, the f-block elements, are used in a wide variety of fields including telecommunications, medicine, imaging, sensors, energy, catalysis, and data storage. However, compared to other blocks in the periodic table, f-elements remain underexplored. Deepening ...
Step-by-Step Solution:1. Understanding F-Block Elements: - F-Block elements are those elements where the last electron enters the f-orbital. These elements are found in the two rows at the bottom of the peri
This chapter discusses molecular properties of transition metals and f -block elements to form metal complexes. It discusses the geometries adopted by metal complexes. A metal complex may be defined as a molecule with n ligands, L , bonded directly to a metal atom or ion, M , via the ...
