The actinide series is part of the seventh row of the periodic table, which is probably the highest row that contains elements stable enough to be identified.
F-block elements The first row is called lanthanides The second row is called actinides
The actinide series encompasses the 15 metallic chemical elements with atomic numbers from 89 to 103, actinium through lawrencium. There are two rows below the periodic table, the first row is lanthanides and the second row is actinides.
Plutonium is a member of the actinides group.
The lanthanides get their name from the element lanthanum, which was the first in the series to be discovered. The actinides get their name from actinium, which was the first element in this series to be discovered.
Uranium is a member of the actinides family.
Plutonium is a member of the actinides group.

The seven horizontal rows of the table are called periods. Elements in the same row have the same number of electron shells, which determines their chemical properties.
Americium is in the Actinide family of elements. It is a synthetic element with the symbol Am and atomic number 95. Actinides are a series of elements in the periodic table that have properties similar to actinium.
Americium is a member of the actinides group.
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.
They are called f-block elements. The first row elements are called lanthanides. The second row elements are called actinides.
