The lanthanides and actinides form a group that appears almost disconnected from the rest of the periodic table this is the f block of elements, known as the inner transition series this is due to the proper numerical position between groups 2 and 3 of the transition metals. ' lanthanide contraction is a term used in chemistry to describe the greater-than-expected decrease in ionic radii of the elements in the lanthanide series from atomic number 57, lanthanum (la), to 71, lutetium (lu). Introduction single-molecule magnets (smms) based on lanthanide ions offer an exciting development towards their potential practical usage, and this field has accordingly attracted enormous attention recently. The lanthanides, elements 58-71, follow lanthanum on the periodic tablethey have electron configurations of 4f x 5d 1 6s 2the lanthanides are all chemically very similar, since each additional electron is added to a lower-lying 4f orbital, thereby not affecting the valence shell.

Introduction liquid metals can be antennas and resonant structures the lanthanides in a liquid phase are complicated metallic systems compared to. 41 introduction lanthanides represent a group of 15 chemically similar elements from lanthanum (la) to lutetium (lu) that are associated with the filling of the 4f shell these 15 lanthanide elements, along with the chemically similar elements scandium and yttrium, are often collectively known as the rare earth (re) elements ( figure 41 . History of the periodic table part 4: lanthanides and actinides - elemental misfits two series of elements - lanthanides and actinides - make up a group called the inner transition metals , falling between groups 2 and 4 on the periodic table (see the single and double asterisks below.
