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.

they are of two types lanthanides and actinides
Where are landthanides and actinides actinides placed in the periodic table?
Lanthanides and Actinides are placed separately as the properties of these elements is quite different from the elements in periodic table.
How many lanthanides and actinides are there?
There are 15 lanthanides (atomic numbers 57-71) and there are 15 actinides (atomic numbers 89-103)
What is the group number for Lanthanides and Actinides?
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.
What elements are placed at the bottom of the periodic table?
The periodic table of elements is a chart that organizes the elements and emphasizes their shared traits and commonalities. All the known elements and their atomic number are on the periodic table.

Why are lanthandies placed below the periodic table?
Lanthanides and actinides are placed below the periodic table because of their unique physical and chemical properties.
