They include elements 57-71, or lanthanides, and 89-103, or actinides. The lanthanides are very similar, and the actinides are all radioactive. Periodic Table.

3 нояб. 2020 г. · The two series of inner transition elements that are 4f and 5f series are known as lanthanoids and actinoids respectively.

9 янв. 2020 г. · Lanthanides and actinides are called inner transition elements because of their placement in the periodic table due to their electronic configuration.

Inner transition metals are those in which inner f-orbital is progressively filled, f-block elements are called inner transition metals.

Inner transition elements are the elements in which the last electron enters in the f-orbital. They generally belong to group 3 in the periodic table.

The lanthanide and actinide elements (the f-block) are called inner transition metals and are sometimes considered to be transition metals as well. Since ...

17 дек. 2020 г. · Inner transition elements are in the f-block, and in the f-orbital have valence electrons. They are the Lanthanides, and the Actinides.
