The f-block elements are placed at the bottom of the periodic table because if they were placed where they belong the periodic table would be too big to fit on a normal sheet of paper.

Where are the lanthanides and actinides placed on the periodic table?
At the bottom of the Periodic Table
What are the two rows of metals that appear at the bottom of the periodic table?
elements 56 through 71 are called the lanthanoids
Where are lanthanides placed on periodic table?
57 to 88
Where do the lanthanides and actinides get their names?
They are the two rows placed at the bottom of the periodic table. The first row is called lanthanides and the second is called actinides. They are also known as f-block elements as the electrons are added in the f-orbitals.
Where do lanthanids and actinides fit into the periodic table?
Lanthanides (elements with atomic number 57-71) and actinides (elements with atomic number 89 to 103) are placed at the bottom of the periodic table.
Were are the lanthanides placed on the periodic table?
After lanthanum, thus the name.
Where are the lanthanides placed in the periodic table?
Lanthanides are placed in a special row under the classical periodic table; but this arrangement is only a convention.
Where are the lanthanides and actinides placed on the periodic table?
At the bottom of the Periodic Table
Where are lanthanides placed on periodic table?
57 to 88
What are the two rows of metals that appear at the bottom of the periodic table?
elements 56 through 71 are called the lanthanoids
What is placed at the bottom of the periodic table because they are too wide to represent the chart form?
f-block elements (lanthanides and actinides)
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.
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.
Where are the lanthanides and actinides places in the periodic table?
they are not placed from elements 57-70.
Why are the elements 57-70 89-102 found seperately at the bottom of the periodic table?
They are lanthanides and actinides. They have different chemical properties , hence they are placed separately.
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.
Where do the lanthanides and actinides get their names?
They are the two rows placed at the bottom of the periodic table. The first row is called lanthanides and the second is called actinides. They are also known as f-block elements as the electrons are added in the f-orbitals.
