The lanthanides and actinides are groups of elements in the periodic table. Uses of Lanthanides . These periods are given these names since the actinide series starts from a chemical called Actinium and the lanthanide series starts from a chemical element called Lanthanum. They are 14 elements which have similar properties. Lanthanides and Actinides Lanthanides and actinides are collectively called f-block elements because last electron in them enters into f-orbitals of … %PDF-1.3 The can also be used for structural-alloy-modifying components of reactors. Like the lanthanides, the actinides form a family of elements with similar properties.Within the actinides, there are two overlapping groups: transuranium elements, which follow uranium in the periodic table—and transplutonium elements, which follow plutonium.Compared to the lanthanides, which (except for promethium) are found in nature in appreciable quantities, most actinides are rare. Fourteen elements from Th(90) to Lw(103) comprise actinide series, and are also called second inner transition series. The actinides are elements 89 to 103 and fill their 5f sublevel progressively.Actinides are typical metals and have properties of both the d-block and the f-block elements, but they are also radioactive.

These elements are grouped together and called the lanthanides. The key difference between actinides and lanthanides is that the actinides fill electrons to 5f sub-orbitals, whereas lanthanides fill electrons up to 4f sub-orbitals.. Lanthanides and actinides occur in two separate rows in the periodic table.Hence, both belong to the f block. These are also called lanthanides or lanthanons. Place the lanthanides and actinides in the periodic table. All these three elements contain a ‘d’ electron in their electronic configuration. Actinides. The chemical elements in the actinide series are called actinides, and the elements in the lanthanide series are called lanthanides. They are also called inner transition metals. The seven orbitals of the f sublevel accommodate 14 electrons, so the f block is 14 elements in length. Define the lanthanides and actinides. The The Lanthanide and Actinide series are at the bottom of the periodic table of elements because if they were where they were supposed to be, then the table would be way too long. It fills after the 6 s sublevel, meaning that f sublevels are two principal energy levels behind. Like the Actinides, the Lanthanides can be used for nuclear purposes.
