lanthanides and actinides are fairly reactive, but not as much as say, the alkali metals in group 1
The main metal groups include alkali metals, alkaline earth metals, transition metals, lanthanides, and actinides. Alkali metals are highly reactive and have low melting points, while alkaline earth metals are also reactive but less so than alkali metals and have higher melting points. Transition metals are known for their ability to form various oxidation states and colored compounds, whereas lanthanides and actinides are characterized by their f-f orbital electron configurations and include elements that are typically radioactive.
Actinides and lanthanides lose electrons and form cations.
The f-block elements in period 7 are known as the actinides.
Group 12 elements on the periodic table are not lanthanides or actinides. They are transition metals, also known as the zinc group, which includes elements like zinc (Zn), cadmium (Cd), and mercury (Hg). Lanthanides and actinides are separate groups that are located in the inner transition metals section of the periodic table.
The alien periodic table does not include alkaline earth metals, transition metals, lanthanides, and actinides because it is a conceptual representation that supposes the existence of different types of elements beyond the known ones on Earth. The purpose is to explore the idea of diversity in chemical elements and atomic structures that may exist in other realms or universes.
The lanthanides and actinides are part of the inner transition metals. Actinides are all radioactive, highly electropositive and tarnish readily in air. Lanthanides burn easily in air, have high melting and boiling points and are strong reducing agents.
Wht is the difference between Lanthanides and Actinides?
Actinides and lanthanides lose electrons and form cations.

Rare Earth elements or lanthanides are placed in the period 6 of the periodic table of Mendeleev. Actinoids are placed in the period 7 of the periodic table of Mendeleev.

Lanthanides and actinides are two series of elements located at the bottom of the periodic table. They are known for their unique electron configurations, with the lanthanides having partially filled 4f orbitals and the actinides having partially filled 5f orbitals. These series contain many rare earth elements and heavy metals with important industrial, medical, and nuclear applications.
